Re: Schema change on Spark Hive (Parquet file format) table not
working
Yes, I've found a number of problems with metadata management in Spark SQL.
One core issue is SPARK-9764
<https://issues.apache.org/jira/browse/SPARK-9764> . Related issues are
SPARK-9342 <https://issues.apache.org/jira/browse/SPARK-9342> , SPARK-9761
<https://issues.apache.org/jira/browse/SPARK-9761> and SPARK-9762
<https://issues.apache.org/jira/browse/SPARK-9762> .
I've also observed a case where, after an exception in ALTER TABLE, Spark
SQL thought a table had 0 rows while, in fact, all the data was still there.
I was not able to reproduce this one reliably so I did not create a JIRA
issue for it.
Let's vote for these issues and get them resolved.
