Kai Zheng created HDFS-9642: ------------------------------- Summary: Create reader threads pool on demand according to erasure coding policy Key: HDFS-9642 URL: https://issues.apache.org/jira/browse/HDFS-9642 Project: Hadoop HDFS Issue Type: Improvement Reporter: Kai Zheng Assignee: Kai Zheng
While investigating some issue it was noticed in {{DFSClient}}, {{STRIPED_READ_THREAD_POOL}} will be always created during initialization and by default regardless the used erasure coding policy it uses the value *18*. This suggests: * Create the thread pool on demand only in striping case. * When create the pool, use a good value respecting the used erasure coding policy. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
