[jira] [Created] (FLINK-9683) inconsistent behaviors when setting
historyserver.archive.fs.dir
Ethan Li created FLINK-9683:
-------------------------------
Summary: inconsistent behaviors when setting historyserver.archive.fs.dir
Key: FLINK-9683
URL: https://issues.apache.org/jira/browse/FLINK-9683
Project: Flink
Issue Type: Bug
Affects Versions: 1.4.2
Reporter: Ethan Li
I am using release-1.4.2,
With fs.default-scheme and fs.hdfs.hadoopconf set correctly,
when setting
{code:java}
historyserver.archive.fs.dir: /tmp/flink/cluster-name/jmarchive
{code}
I am seeing
{code:java}
2018-06-27 18:51:12,692 WARN org.apache.flink.runtime.webmonitor.history.HistoryServer - Failed to create Path or FileSystem for directory '/tmp/flink/cluster-name/jmarchive'. Directory will not be monitored.
java.lang.IllegalArgumentException: The scheme (hdfs://, file://, etc) is null. Please specify the file system scheme explicitly in the URI.

{code}
And then if I set
{code:java}
historyserver.archive.fs.dir: hdfs:///tmp/flink/cluster-name/jmarchive{code}
I am seeing:
{code:java}
java.io.IOException: The given file system URI (hdfs:///tmp/flink/cluster-name/jmarchive) did not describe the authority (like for example HDFS NameNode address/port or S3 host). The attempt to use a configured default authority failed: Hadoop configuration for default file system ('fs.default.name' or 'fs.defaultFS') contains no valid authority component (like hdfs namenode, S3 host, etc)

{code}
The only way it works is to provide the full path of hdfs like:
{code:java}
#historyserver.archive.fs.dir: hdfs://<hdfs-cluster>/tmp/flink/cluster-name/jmarchive
{code}
Above situations are because there are two parts of code treating "scheme" differently.
https://github.com/apache/flink/blob/release-1.4.2/flink-runtime/src/main/java/org/apache/flink/runtime/webmonitor/WebMonitorUtils.java#L299-L302
https://github.com/apache/flink/blob/release-1.4.2/flink-core/src/main/java/org/apache/flink/core/fs/FileSystem.java#L335-L338
I believe the first case should be supported if users have set fs.default-scheme
