Kousuke Saruta created SPARK-19909:
--------------------------------------
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

org.apache.hadoop.security.AccessControlException: Permission denied: user=kou,

{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.
