>
> Currently when copyService.copy() returns non-zero return value, we throw
> exception:
> {code}
> throw new IOException("Failed of Hadoop Distributed Copy from "+
> StringUtils.join(incrBackupFileList, ",") +" to "
> + backupContext.getHLogTargetDir());
> {code}
> We should retry distcp job when the return value is non-zero instead of
> throwing IOException immediately.
