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)
