             Summary: Spark History server doesn't support HDFS HA
                 Key: SPARK-21470
                 URL: https://issues.apache.org/jira/browse/SPARK-21470
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 2.2.0
            Reporter: Maciej Bryński


With Spark version up to 2.1.1 there was possibility to config history server to read from hdfs without putting namenode:
spark.history.fs.logDirectory hdfs:///apps/spark
And this works with HDFS HA.

Unfortunately there is regression with Spark 2.2.0 when such configuration gives error:
{code}
Caused by: java.io.IOException: Incomplete HDFS URI, no host: hdfs:///apps/spark
