>
> Key: SPARK-31995
> URL: https://issues.apache.org/jira/browse/SPARK-31995
> Project: Spark
> Issue Type: Bug
> Components: Structured Streaming
> Affects Versions: 2.4.5
> Environment: Apache Spark 2.4.5 Scala 2.11 without Hadoop
> Hadoop 2.7.3 - YARN cluster
> delta-core_ 2.11:0.6.1
>
> Reporter: Jim Huang
> Priority: Major
>
> I am using Spark 2.4.5's Spark Structured Streaming with Delta table (0.6.1)
> as the sink running in YARN cluster running on Hadoop 2.7.3. I have been
> using Spark Structured Streaming for several months now in this runtime
> environment until this new corner case that handicapped my Spark structured
> streaming job in partial working state.
>
> I have included the ERROR message and stack trace. I did a quick search
> using the string "MicroBatchExecution: Query terminated with error" but did
> not find any existing Jira that looks like my stack trace.
>
> Based on the naive look at this error message and stack trace, is it possible
> the Spark's CheckpointFileManager could attempt to handle this HDFS exception
> better to simply wait a little longer for HDFS's pipeline to complete the
> replicas?
>
> Being new to this code, where can I find the configuration parameter that
> sets the replica counts for the `streaming.HDFSMetadataLog`? I am just
> trying to understand if there are already some holistic configuration tuning
> variable(s) the current code provide to be able to handle this IOException
> more gracefully? Hopefully experts can provide some pointers or directions.
