ANALYZE TABLE ... COMPUTE STATISTICS PARTIALSCAN removed

The analyze command collects statistics on tables and partitions, but is slow when scanning many files. A command was added that operated on files in RCfile format to speed up statistics collection. The command was not widely used, not well documented, and evenutally removed.

Before Upgrade to CDP

ANALYZE TABLE ... COMPUTE STATISTICS PARTIALSCAN was added to Hive to collect statistics, not by scanning all content of files, but by scanning only parts to get file metadata. Examples are shown in https://cwiki.apache.org/confluence/display/Hive/RCFileCat.

After Upgrade to CDP

HIVE-17652 removes this syntax in release 3.0.0.

Action Required

In the unlikely event you used this command, remove it from your code.
