stack commented on HBASE-20604: ------------------------------- [~esteban] See above. Should we reopen this issue since outstanding review? > ProtobufLogReader#readNext can incorrectly loop to the same position in the > stream until the the WAL is rolled > -------------------------------------------------------------------------------------------------------------- > > Key: HBASE-20604 > URL: https://issues.apache.org/jira/browse/HBASE-20604 > Project: HBase > Issue Type: Bug > Components: Replication, wal > Affects Versions: 3.0.0 > Reporter: Esteban Gutierrez > Assignee: Esteban Gutierrez > Priority: Critical > Fix For: 3.0.0, 1.5.0, 1.3.3, 2.2.0, 2.0.3, 1.4.9, 2.1.2, 1.2.9 > > Attachments: HBASE-20604.002.patch, HBASE-20604.003.patch, > HBASE-20604.004.patch, HBASE-20604.005.patch, HBASE-20604.patch > > > Every time we call {{ProtobufLogReader#readNext}} we consume the input stream > associated to the {{FSDataInputStream}} from the WAL that we are reading. > Under certain conditions, e.g. when using the encryption at rest > ({{CryptoInputStream}}) the stream can return partial data which can cause a > premature EOF that cause {{inputStream.getPos()}} to return to the same > origina position causing {{ProtobufLogReader#readNext}} to re-try over the > reads until the WAL is rolled. > The side effect of this issue is that {{ReplicationSource}} can get stuck > until the WAL is rolled and causing replication delays up to an hour in some > cases. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
