This change modifies the output of the SHOW TABLE STATS and SHOW PARTITIONS for Kudu tables. - PARTITIONS: the #Row column has been removed - TABLE STATS: instead of showing partition informations it returns a resultset similar to HDFS table stats, #Rows, #Partitions, Size, Format and Location Example outputs can be seen in the doc changes. Testing: * kudu_stats.test is modified to verify the new result set * kudu_partition_ddl.test is modified to verify the new partitions style * Updated unit test with the new error message Change-Id: Ice4b8df65f0a53fe14b8fbe35d82c9887ab9a041 Reviewed-on: http://gerrit.cloudera.org:8080/15199 Reviewed-by: Thomas Tauber-Marshall <tmarshall@cloudera.com> Tested-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com>
