[jira] [Commented] (IMPALA-10774) Collect the output each time when
starting Hive metastore or HiveServer2

IMPALA-10774: Collect the output when starting Hive Metastore or HiveServer2
Before this patch, when we started the Hive Metastore or the HiveServer2
via run-hive-server.sh, hive-metastore.out and hive-server2.out would be
generated, respectively. The output of executing the hive command was
redirected to the corresponding files mentioned above. However, since
">" was used to redirect the output, the previously generated files
would be overwritten every time during the restart and thus some
important error message may be lost.
To collect more information regarding the restart, this patch appends
the newly produced output to hive-metastore.out and hive-server2.out
during the restart, which makes it easier for developers to troubleshoot
issues related to the restart.

> Currently when we start the Hive Metastore or the HiveServer2 via {{run-hive-server.sh}}, {{hive-metastore.out}} and {{hive-server2.out}} will be generated, respectively. The output of executing the {{hive}} command will be redirected to the corresponding files mentioned above. However, since "{{>}}" is used to redirect the output, the previously generated files will be overwritten every time when the Hive Metastore or the HiveServer2 are restarted and thus some important error message may be lost during the restart.
> Recall that the restart of the Hive Metastore or the HiveServer2 occurs several times during the E2E tests. To facilitate the debugging of issues related to the restart, it is better to append the newly produced output to the corresponding output files rather than overwriting the previously generated ones.
