Thanks Anupam! > Hadoop ignores old-style config options for enabling compressed output > ---------------------------------------------------------------------- > > Key: HADOOP-7993 > URL: https://issues.apache.org/jira/browse/HADOOP-7993 > Project: Hadoop Common > Issue Type: Bug > Components: conf > Affects Versions: 0.23.1 > Reporter: Anupam Seth > Assignee: Anupam Seth > Attachments: HADOOP-7993_branch_0_23.patch, > HADOOP-7993_branch_0_23.patch > > > Hadoop seems to ignore the config options even though they are printed as > deprecation warnings in the log: mapred.output.compress and > mapred.output.compression.codec > - settings that work on 0.20 but not on 0.23 > mapred.output.compress=true > mapred.output.compression.codec=org.apache.hadoop.io.compress.BZip2Codec > - settings that work on 0.23 > mapreduce.output.fileoutputformat.compress=true > mapreduce.output.fileoutputformat.compress.codec=org.apache.hadoop.io.compress.BZip2Codec > This breaks backwards compatibility and causes existing jobs to fail. > This was found to happen due to the JobSubmitter writing out the job.xml file > with the old-style configs and can be fixed by handdling deprecation before > the file is written out. -- This message is automatically generated by JIRA.
