["Abhishek Chennaka (Code Review)" <ge...@cloudera.org>]

Hello Kudu Jenkins, Andrew Wong,

to look at the new patch set (#2).

[tools] KUDU-3333 Include Table Counts in kudu hms Dryrun

In cases where the user running the Kudu CLI tool, kudu hms
fix, doesn't have permissions from Ranger/Sentry to access
the tables, these tables would be treated as non-existant tables
in Kudu. In such scenarios, there might be situations where the
tables could be dropped from HMS inspite of them being present
in Kudu when run with -drop_orphan_tables flag.

This patch adds additional logging which reports the total
table counts from HMS and Kudu master catalogs and warns the
user if there are no tables in Kudu when kudu hms fix command is
run.

Sample runs of the tool after the change:
I0315 16:16:36.039008 351197 tool_action_hms.cc:867] Number of Kudu tables found in Kudu master catalog: 0
I0315 16:16:36.039080 351197 tool_action_hms.cc:868] Number of Kudu tables found in HMS catalog: 0
I0315 16:16:55.158463 351291 tool_action_hms.cc:642] NOTE: There are zero kudu tables listed. If the cluster indeed has kudu tables please re-run the command with right credentials.
I0315 16:16:55.158546 351291 tool_action_hms.cc:867] Number of Kudu tables found in Kudu master catalog: 0
