Review Comment:
`rewritePolicy = ALL_PARTITIONS` is added in case of full table compaction
for partitioned and unpartitioned tables.
`HiveConf.setVar(conf, HiveConf.ConfVars.REWRITE_POLICY,
Context.RewritePolicy.PARTITION.name());`
Is added for partition compaction case only. This code branch is reachable
only when `partitionSpecNode != null` and `command.getType() ==
HiveParser.TOK_ALTERTABLE_COMPACT`
