Hi Devs, We have seen couple of Block missing issues in stress testing. ( mostly all were with default configurations )
1) HDFS-3584 Blocks are getting marked as corrupt with append operation under high load. 2) HDFS-3585 Blocks are getting marked as corrupt when commitblocksyncronization(Since recovery called by another client) is success before BR send 3) HDFS-3122 Block recovery with closeFile flag true can race with blockReport. Due to this blocks are getting marked as corrupt. 4) HDFS-3605 Block mistakenly marked corrupt during edit log catchup phase of failover ===== Already Fixed I would like your involvement in the discussion and comments on this issues for the further progress. Regards, Uma
