Subject Pluggable SecondaryFileSystemProvider?
Date Thu, 17 Dec 2015 19:14:52 GMT
Hi, dev,
one of Ignite users discovered that IGFS does not correctly work with
secondary HDFS file system if that HDFS is "kerberised". The issue is
described in https://issues.apache.org/jira/browse/IGNITE-2195 (This may
also be close to this issue:
http://apache-ignite-users.70518.x6.nabble.com/Exception-in-Kerberos-Yarn-cluster-td1950.html
). The user suggests a fix that creates SecondaryFileSystem using some
proxy UserGroupInformation, and that workaround works for him.
However, we're not sure this fix is generic enough and will work well in
all possible configurations.
So, there is an idea to make SecondaryFileSystemProvider pluggable to allow
users to write own code for specific configurations. An example can be seen
in this pull request:
https://github.com/apache/ignite/pull/350 .
Pros, cons, other thoughts?
Thanks in advance.
