> HIVE-3958 added support for partial scan for RCFile. This works fine for static partitions
(for example: analyze table analyze_srcpart_partial_scan PARTITION(ds='2008-04-08',hr=11)
compute statistics partialscan).
> For dynamic partition, the analyze files with an IOException "java.io.IOException: No
input paths specified in job":
> hive> ANALYZE TABLE testtable PARTITION(col_varchar) COMPUTE STATISTICS PARTIALSCAN;
> java.io.IOException: No input paths specified in job
