Ted Yu commented on HBASE-19435: -------------------------------- lgtm > Reopen Files for ClosedChannelException in BucketCache > ------------------------------------------------------ > > Key: HBASE-19435 > URL: https://issues.apache.org/jira/browse/HBASE-19435 > Project: HBase > Issue Type: Bug > Components: BucketCache > Affects Versions: 2.0.0, 1.3.1 > Reporter: Zach York > Assignee: Zach York > Attachments: HBASE-19435.master.001.patch, > HBASE-19435.master.002.patch, HBASE-19435.master.003.patch, > HBASE-19435.master.004.patch, HBASE-19435.master.005.patch > > > When using the FileIOEngine for BucketCache, the cache will be disabled if > the connection is interrupted or closed. HBase will then get > ClosedChannelExceptions trying to access the file. After 60s, the RS will > disable the cache. This causes severe read performance degradation for > workloads that rely on this cache. FileIOEngine never tries to reopen the > connection. This JIRA is to reopen files when the BucketCache encounters a > ClosedChannelException. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
