Summary: 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: 1.3.1, 2.0.0
Reporter: Zach York
Assignee: Zach York
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.
