Custom Partitioner not working in Oozie Mapreduce action -


i have implemented secondary sort in mapreduce , trying execute using oozie (from hue).

though have set partitioner class in properties, partitioner not being executed. so, i'm not getting output expected.

the same code runs fine when run using hadoop command.

and here workflow.xml

<workflow-app name="mytriplets" xmlns="uri:oozie:workflow:0.5"> <start to="mapreduce-598d"/> <kill name="kill">     <message>action failed, error message[${wf:errormessage(wf:lasterrornode())}]</message> </kill> <action name="mapreduce-598d">     <map-reduce>         <job-tracker>${jobtracker}</job-tracker>         <name-node>${namenode}</name-node>         <configuration>             <property>                 <name>mapred.output.dir</name>                 <value>/test_1109_3</value>             </property>             <property>                 <name>mapred.input.dir</name>                 <value>/apps/hive/warehouse/7360_0609_rx/day=06-09-2017/hour=13/quarter=2/,/apps/hive/warehouse/7360_0609_tx/day=06-09-2017/hour=13/quarter=2/,/apps/hive/warehouse/7360_0509_util/day=05-09-2017/hour=16/quarter=1/</value>             </property>             <property>                 <name>mapred.input.format.class</name>                 <value>org.apache.hadoop.hive.ql.io.rcfileinputformat</value>             </property>             <property>                 <name>mapred.mapper.class</name>                 <value>ponrankmapper</value>             </property>             <property>                 <name>mapred.reducer.class</name>                 <value>ponrankreducer</value>             </property>             <property>                 <name>mapred.output.value.comparator.class</name>                 <value>ponrankgroupingcomparator</value>             </property>             <property>                 <name>mapred.mapoutput.key.class</name>                 <value>ponrankpair</value>             </property>             <property>                 <name>mapred.mapoutput.value.class</name>                 <value>org.apache.hadoop.io.text</value>             </property>             <property>                 <name>mapred.reduce.output.key.class</name>                 <value>org.apache.hadoop.io.nullwritable</value>             </property>             <property>                 <name>mapred.reduce.output.value.class</name>                 <value>org.apache.hadoop.io.text</value>             </property>             <property>                 <name>mapred.reduce.tasks</name>                 <value>1</value>             </property>             <property>                 <name>mapred.partitioner.class</name>                 <value>ponrankpartitioner</value>             </property>             <property>                 <name>mapred.mapper.new-api</name>                 <value>false</value>             </property>         </configuration>     </map-reduce>     <ok to="end"/>     <error to="kill"/> </action> <end name="end"/>

when running using hadoop jar command, set partitioner class using jobconf.setpartitionerclass api.

not sure why partitioner not executed when running using oozie. inspite of adding 

            <property>                 <name>mapred.partitioner.class</name>                 <value>ponrankpartitioner</value>             </property>

any i'm missing when running oozie ??

solved re-writing mapreduce job using new api's.

the property used in oozie workflow partitioner mapreduce.partitioner.class.

minify - Minimizing css files -

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
