Andrew Purtell created HBASE-17780: -------------------------------------- Summary: BoundedByteBufferPool "At capacity" messages are not actionable Key: HBASE-17780 URL: https://issues.apache.org/jira/browse/HBASE-17780 Project: HBase Issue Type: Bug Affects Versions: 1.3.0 Reporter: Andrew Purtell Assignee: Andrew Purtell Priority: Minor Fix For: 1.31, 2.0.0, 1.4.0
This comment in BoundedByteBufferPool talks about "At capacity ..." warnings from this class that may appear in logs when under load: {code} * If a ByteBuffer is bigger than the configured threshold, we will just let the ByteBuffer go * rather than add it to the pool. If more ByteBuffers than the configured maximum instances, * we will not add the passed ByteBuffer to the pool; we will just drop it * (we will log a WARN in this case that we are at capacity). {code} First, dropping buffers when the pool is full is obviously an expected and normal condition. Second, there is nothing actionable about that warning. Might be useful for developers, perhaps. Drop it to DEBUG. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
