---------------------------------
Summary: Shell alter command (modify operation) sometimes times out
Key: HBASE-25974
URL: https://issues.apache.org/jira/browse/HBASE-25974
Project: HBase
Issue Type: Bug
Components: Client, shell
Affects Versions: 2.2.4, 2.1.4
Reporter: Rod Prada
Attachments: hbase-shell-alter-failure.tar.gz
Execution of an alter command like the following on a non-interactive shell
sometimes times out:
{code:java}
echo "alter 'aeris_v2', {NAME=>'e', VERSIONS=>'43200', MIN_VERSIONS=>'3',
TTL=>'7776000'}, NANOSECOND_TIMESTAMPS => 'true'" | hbase shell -n{code}
A similar issue was reported in
[HBASE-21795|https://issues.apache.org/jira/browse/HBASE-21795], but based on
its description it should be resolved on the HBase versions we are running
(2.1.4, 2.2.4).
The hbasemaster and regionserver logs attached are relevant to one occurrence
of the issue when the command started at 2021-05-29 05:25 and timed out 10
minutes later at 2021-05-29 05:35.
Note that the affected table appeared to be modified even though the shell
command timed out.
The hbase shell debug output attached is from another similar failure where we
managed to toggle the shell d flag to capture extra debug information. The
capture indicates the zookeeper client session being closed at the 1-minute
mark and the command failing at the 10-minute mark with a timeout.
If there is a way to output even more debugging information (e.g. stack traces)
from the shell process other than specifying the "d" flag to help troubleshoot
the issue, please let us know.
