Sean Busbey commented on HBASE-13221: ------------------------------------- Additionally, when this was falling over it pointed out that the exception catching in AsyncWriter / AsyncSyncer needs to be more robust. We got IndexOutOfBoundsException and InternalError (!!), both of which caused the Writer / Syncer thread to exit. This deadlocked the RS since nothing could ever notify that WAL writes had completed. > HDFS Transparent Encryption breaks WAL writing > ---------------------------------------------- > > Key: HBASE-13221 > URL: https://issues.apache.org/jira/browse/HBASE-13221 > Project: HBase > Issue Type: Bug > Components: wal > Affects Versions: 0.98.0, 1.0.0 > Reporter: Sean Busbey > Assignee: Sean Busbey > Priority: Blocker > Fix For: 2.0.0, 1.0.1, 1.1.0, 0.98.12 > > > We need to detect when HDFS Transparent Encryption (Hadoop 2.6.0+) is enabled > and fall back to more synchronization in the WAL to prevent catastrophic > failure under load. > See HADOOP-11708 for more details. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
