Summary: Print hdfs pipeline when hlog's sync is slow
Key: HBASE-11240
URL: https://issues.apache.org/jira/browse/HBASE-11240
Project: HBase
Issue Type: Improvement
Components: wal
Reporter: Liu Shaohui
Assignee: Liu Shaohui
Sometimes the slow sync of hlog writer is because there is an abnormal datanode
in the pipeline. So it will be helpful to print the pipeline of slow sync to
diagnose those problems.
The ultimate solution is to join the trace of HBase and HDFS.
