> Looking at the code in DeployCoprocessorCLI.java and HtableAlterMetadataCLI.java , I
see that close of Admin instance is without finally block:
> {code}
>         hbaseAdmin.disableTable(table.getTableName());
>         table.setValue(metadataKey, metadataValue);
>         hbaseAdmin.modifyTable(table.getTableName(), table);
>         hbaseAdmin.enableTable(table.getTableName());
>         hbaseAdmin.close();
> {code}
> If any exception is thrown in the operations prior to the close(), the close() would
be skipped, leading to resource leak.
