-----------------------------
Summary: CLONE - Fix the editlog corruption exposed by failed
TestAddStripedBlocks
Key: HDFS-10024
URL: https://issues.apache.org/jira/browse/HDFS-10024
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: dragon
Assignee: Jing Zhao
Fix For: HDFS-7285
{{TestAddStripedBlocks}} failed with some editlog corruption. Did some
debugging, I can see at least two issues:
# DFSStripedOutputStream tries to send out an empty packet to close the block
even if writing 0 bytes
# Because of the above, NN tries to close the file. This exposes another bug in
{{BlockInfoStriped}}, which writes its data/parity block numbers into the close
editlog but do not read them while loading.
This jira aims to only fix #2 and HDFS-8166 is used for fixing #1.
