URL: https://github.com/apache/hive/pull/1434
### What changes were proposed in this pull request?

blocks

when reading the Avro file which has a bad file format in Hive, we want to
skip the invalid sync errors simply
https://issues.apache.org/jira/browse/HIVE-16352
### Does this PR introduce _any_ user-facing change?
NO. The default value of AVRO_SERDE_ERROR_SKIP is false keeping the original
