Subject [Impala-ASF-CR] IMPALA-4282: Remove max length check for type strings.
Date Fri, 17 Feb 2017 05:30:10 GMT
Impala Public Jenkins has submitted this change and it was merged.

Change subject: IMPALA-4282: Remove max length check for type strings.

IMPALA-4282: Remove max length check for type strings.

During analysis, Impala used to enforce the default HMS
limit on the number of characters of a type string.
That enforcement has the benefit of a clear error
message, but has the severe drawback of not having
any workaround because the limit is baked into the code.
Going above the 4000 limit is pretty easy with complex
types, and several users have already run into this

This patch removes the Impala-side enforcement such
that the 4000 limit can be increased by altering
the corresponding columns in the Metastore's backend
