-----------------------------------
Summary: Error while checkpointing to HDFS (similar to JIRA
SPARK-19268)
Key: SPARK-20894
URL: https://issues.apache.org/jira/browse/SPARK-20894
Project: Spark
Issue Type: Bug
Components: Structured Streaming
Affects Versions: 2.1.1
Environment: Ubuntu, Spark 2.1.1, hadoop 2.7
Reporter: kant kodali
Dataset<Row> df2 = df1.groupBy(functions.window(df1.col("Timestamp5"), "24
hours", "24 hours"), df1.col("AppName")).count();
StreamingQuery query = df2.writeStream().foreach(new
KafkaSink()).option("checkpointLocation","/usr/local/hadoop/checkpoint").outputMode("update").start();
query.awaitTermination();
This for some reason fails with the Error
ERROR Executor: Exception in task 0.0 in stage 1.0 (TID 1)
java.lang.IllegalStateException: Error reading delta file
/usr/local/hadoop/checkpoint/state/0/0/1.delta of HDFSStateStoreProvider[id =
(op=0, part=0), dir = /usr/local/hadoop/checkpoint/state/0/0]:
/usr/local/hadoop/checkpoint/state/0/0/1.delta does not exist
I did clear all the checkpoint data in /usr/local/hadoop/checkpoint/ and all
consumer offsets in Kafka from all brokers prior to running and yet this error
still persists.
