Subject [jira] Created: (HBASE-1791) Timeout in IndexRecordWriter
Date Tue, 25 Aug 2009 16:27:59 GMT
Timeout in IndexRecordWriter

                 Key: HBASE-1791
                 URL: https://issues.apache.org/jira/browse/HBASE-1791
             Project: Hadoop HBase
          Issue Type: Bug
    Affects Versions: 0.20.0, 0.20.1, 0.21.0
         Environment: 19 HBase nodes, 8 cores, 8 GB RAM, CentOS
            Reporter: Bradford Stephens
            Priority: Minor

A MapReduce job to generate Lucene Indexes from HBase will fail on sufficiently large tables.
After the indexing finished, the close() method of IndexRecordWriter is called.  The  writer.optimize()
call in this method can take many minutes, forcing most MapReduce tasks to timeout. There
is a HeartBeatsThread, but it does not seem to send progress updates. 

A suggested fix may be to add context.progress(); in the HeardbeatsThread run() method, after
the context.setStatus call. Not sure why context.setStatus is not "good enough".
