             Summary: Batches will fail in case that temporary checkpoint dir is on local file system while metadata dir is on HDFS
                 Key: SPARK-19909
                 URL: https://issues.apache.org/jira/browse/SPARK-19909
             Project: Spark
          Issue Type: Bug
          Components: Structured Streaming
    Affects Versions: 2.2.0
            Reporter: Kousuke Saruta
            Priority: Minor


When we try to run Structured Streaming in local mode but use HDFS for the storage, batches will be fail because of error like as follows.

{code}
val handle = stream.writeStream.format("console").start()
17/03/09 16:54:45 ERROR StreamMetadata: Error writing stream metadata StreamMetadata(fc07a0b1-5423-483e-a59d-b2206a49491e) to /private/var/folders/4y/tmspvv353y59p3w4lknrf7cc0000gn/T/temporary-79d4fe05-4301-4b6d-a902-dff642d0ddca/metadata
org.apache.hadoop.security.AccessControlException: Permission denied: user=kou, access=WRITE, inode="/private/var/folders/4y/tmspvv353y59p3w4lknrf7cc0000gn/T/temporary-79d4fe05-4301-4b6d-a902-dff642d0ddca/metadata":hdfs:supergroup:drwxr-xr-x
{code}

It's because that a temporary checkpoint directory is created on local file system but metadata whose path is based on the checkpoint directory will be created on HDFS.
