[I am seeing this same issue without standby
JMs|https://lists.apache.org/thread/24228yww7bz5kskx5zkjt1fwkvh47dqs], at some
point the JM pod restarts and then all checkpoints and savepoints fail even if
I restart all JM and TM pods manually.
[~_anton] where did you set {{fs.azure.data.blocks.buffer}}? Does Flink forward
it if I place that in {{flink-conf.yaml}}?

I think the root cause maynot similar to FLINK-30635.
I suspect it may be caused by the different class loader.

I'm trying to understand why `ServiceLoader.load(FileSystem.class)` is empty.
I'm not very sure, but from the stack strace and flink plugin mechanism, the
class `FileSystem` is loaded by `PluginClassLoader`, and
`ServiceLoader.load(FileSystem.class)` will try to use `
Thread.currentThread().getContextClassLoader()` which maybe appclassloader to
load the `FileSystem.class`. Since they are different classloaders, the result
is empty.
If that's the case, I think you may can set
`plugin.classloader.parent-first-patterns.additional` = `org.apache.hadoop.`
to enforce FileSystem.class to be loaded by appclassloader.

+1 it's similar to FLINK-30635.
setting {{fs.azure.data.blocks.buffer}} to {{array}} makes abfs use memory to
cache instead of local disk so that it doesn't need localfilesystem.
it may also works if setting _fs.file.impl_ to
_org.apache.hadoop.fs.LocalFileSystem.class.getName()_ explicitly (It may be a
shaded path).

[jira] [Commented] (FLINK-32241) UnsupportedFileSystemException when using the ABFS Hadoop driver for checkpointing in Flink 1.17
[
https://issues.apache.org/jira/browse/FLINK-32241?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17728393#comment-17728393

Steve Loughran commented on FLINK-32241:
this is odd as the buffer to disk code is derived from what's been in the s3a
connector for years and it never blew up.
on a host without the abfs change, can you grab the cloudstore module and run
its storediag command to get a view of the world, including probes of temp dirs
... look for the output under "Output Buffering" to see

>Affects Versions: 1.17.0, 1.17.1

> It looks like this breaks with Flink 1.17 in a scenario where:
> * ABFS is used for checkpointing
> * JobManager HA is enabled
> * First JobManager leader dies and a stand-by JobManager takes over
> I can reliably reproduce this with Flink 1.17.1 running on Kubernetes by
> simply killing the JM leader pod. Once the stand-by JobManager takes over,
> all checkpoints consistently fail with the following error:
