Xinglong Wang commented on HUDI-3425:
-------------------------------------
I have encountered the same problem. I am using Flink on Yarn. When the job
executes compaction but encounters an abnormal situation (for example,
container is running beyond physical memory limits or other exceptions) and
performs a full-restart, if `HoodieMergedLogRecordScanner` is still scanning
log files at this time, and `ExternalSpillableMap#close()` is not executed to
clean up, resulting in the accumulation of spillable map files in the /tmp
directory, and eventually the disk is exhausted.
Now I set `hoodie.memory.spillable.map.path` to the `$PWD/spillable-map/`
directory when Yarn container launches, environment variable `PWD` is exported
in `launch_container.sh`, so that the spillable map files will be cleaned up
when the container is closed.

> h1. Hudi spill path not getting cleared when containers getting killed
> abruptly.
>
> When yarn kills the containers abruptly for any reason while hudi stage is in
> progress then the spill path created by hudi on the disk is not cleaned and
> as a result of which the nodes on the cluster start running out of space. We
> need to clear the spill path manually to free out disk space.
