String partitions that start with spaces or numbers cause errors
----------------------------------------------------------------
Key: HIVE-1637
URL: https://issues.apache.org/jira/browse/HIVE-1637
Project: Hadoop Hive
Issue Type: Bug
Affects Versions: 0.7.0
Environment: java 1.6
Reporter: Raviv M-G
Priority: Minor
When a string partition starts with a space or with a number joins on that
table or selecting one field from that table will cause errors. You can,
however, still perform partition specific queries without a problem.

Job Submission failed with exception 'java.lang.IllegalArgumentException(Can

And attempting to rename a table with such a partition causes:
hive> alter table researchaddress rename to researchaddress2;
Invalid alter operation: Old partition location is invalid.
