[jira] [Created] (FLINK-19121) Avoid access HDFS in HiveBulkWriterFactory

Jingsong Lee created FLINK-19121:
------------------------------------

             Summary: Avoid access HDFS in HiveBulkWriterFactory
                 Key: FLINK-19121
                 URL: https://issues.apache.org/jira/browse/FLINK-19121
             Project: Flink
          Issue Type: New Feature
          Components: Connectors / Hive
    Affects Versions: 1.11.1, 1.12.0
            Reporter: Jingsong Lee


In HadoopPathBasedBulkWriter, getSize will invoke `FileSystem.exists` and `FileSystem.getFileStatus`, but it is invoked per record.

There will be lots of visits to HDFS, may make HDFS pressure too high.
