Subject [jira] [Created] (SPARK-15056) Issue Better Exception for Unsupported Sampling
Date Mon, 02 May 2016 07:40:12 GMT
Xiao Li created SPARK-15056:

             Summary: Issue Better Exception for Unsupported Sampling
                 Key: SPARK-15056
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.0.0
            Reporter: Xiao Li
            Priority: Minor

Compared with the current Spark parser, there are two extra syntax are supported in Hive for

1. In On clauses, rand() indicating sampling on the entire row instead of an individual column.

2. Users can specify total length to be read in block_sample.

We need to parse and capture them. Issue a better error message for these unsupported features.
