Summary: RBF: Fix putAll impl for mysql and file based state stores
Key: HDFS-17041
URL: https://issues.apache.org/jira/browse/HDFS-17041
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Viraj Jasani
Assignee: Viraj Jasani
Only zookeeper based state store allows all records to be inserted even though
only few of them already exists and "errorIfExists" is true, however file/fs as
well as mysql based putAll fails the whole putAll operation immediately after
encountering single record that already exists in the records and
"errorIfExists" is provided true (which is the case while inserting records for
the first time).
For all implementations, we should allow inserts of the records that do not
already exist and report any record as failure that already exists, rather than
failing the whole operation and not trying to insert valid records.
