Marcelo Vanzin commented on SPARK-21470:
----------------------------------------
That still looks like some issue in your configuration. Seems like the HDFS
library doesn't know that "hdfs1" is supposed to be an HA namespace and not a
host. e.g., in one of our clusters we have:
core-site.xml:
{code}
<property>
<name>fs.defaultFS</name>
<value>hdfs://ns1</value>
</property>
{code}
hdfs-site.xml:
{code}
<property>
<name>dfs.nameservices</name>
<value>ns1</value>
</property>
<property>
<name>dfs.ha.namenodes.ns1</name>
<value>namenode19,namenode242</value>
</property>
{code}
Along with a lot of other HA-related configs.
> [SPARK 2.2 Regression] 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
