JobHistory.log and DefaultJobHistory.MasterIndex are missing in 0.17 dev
------------------------------------------------------------------------
Key: HADOOP-3271
URL: https://issues.apache.org/jira/browse/HADOOP-3271
Project: Hadoop Core
Issue Type: Bug
Components: mapred
Environment: Red Hat Enterprise Linux AS release 4 (Nahant Update 5),
JVM 1.5.0_15, hadoop 0.17.0-dev-version 3
Reporter: Eric Yang
Priority: Blocker
There used to be JobHistory.log (MasterIndex in Default HistoryParser class) in
0.15.3 to 0.16.2 which provides the high level overview of the job history.
For HADOOP-2178, this information is no longer being provided by the
DefaultHistoryParser class. In addition, the parser class can only read job
log files from dfs, not from an input stream.
For performance monitoring, we have programs that depends on the pure parser
class and JobHistory.log to extract job information. Please continue to
provide a pure parser class and equivalent function of the JobHistory.log.
