----------------------------
Summary: Imporve logging of block tranaction in tserver's lock
manager
Key: KUDU-3284
URL: https://issues.apache.org/jira/browse/KUDU-3284
Project: Kudu
Issue Type: Improvement
Components: tablet
Reporter: mintao
When multiple client updates same row simultaneously，there will incur a high
contention and degrade perfermance of tserver.The current version provides less
information and makes it hard to diagnose which tablet cause high contention.
{code:java}
W0511 02:05:10.302363 192070 lock_manager.cc:368] Waited 53 seconds to obtain
row lock on key <redacted> cur holder: 0xfc7096c0
{code}
It would be nice if includes tabletID in the logging of blocking transaction
and adds a metric about lock acquisition time about each tablet.
