Log Message: |
Merge trunk into HDFS-1073.
Resolved several conflicts due to merge of HDFS-2149 and HDFS-2212.
Changes during resolution were:
- move the writing of the transaction ID out of EditLogOutputStream to
FSEditLogOp.Writer to match trunk's organization
- remove JSPOOL related FsEditLogOp subclasses, add LogSegmentOp subclasses
- modify TestEditLogJournalFailures to not keep trying to use streams after
the simulated halt, since newer stricter assertions caused these writes to
fail
