> 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
> Priority: Major
> Labels: pull-request-available
>
> 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.
