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.
