[FLINK-5178] allow BlobCache to use a distributed file system irrespective of the HA mode Allow the BlobServer and BlobCache to use a distributed file system for distributing BLOBs even if not in HA-mode. For this, we always try to use the path given by the `high-availability.storageDir` config option and, if accessible, set it up appropriately.

This way the load is more distributed among the nodes of the file system (depending on its implementation of course) compared to putting all the burden on a single BlobServer. commit 389eaa9779d4bf22cc3972208d4f35ac7a966f5c Author: Nico Kruber <n...@data-artisans.com> Date: 2017-01-06T16:21:05Z [FLINK-5129] add unit tests for the BlobCache accessing the distributed FS directly commit b3bcf944df87f37cccd831e8fb56b95caa620dad Author: Nico Kruber <n...@data-artisans.com> Date: 2017-01-09T13:41:59Z [FLINK-5129] let FileSystemBlobStore#get() remove the target file on failure If the copy fails, an IOException was thrown but the target file remained and was (most likely) not finished. This cleans up the file in that case so that code above, e.g. BlobServer and BlobCache, can rely on a file being complete as long as it exists. commit 7ef11131a45a4a84dace06f5984f7b008278857b Author: Nico Kruber <n...@data-artisans.com> Date: 2017-01-06T16:30:39Z [FLINK-5178] move ZookeeperHaServices#createBlobStore to BlobUtils This way of creating a HA distributed blob store is not restricted to Zookeeper and should thus be in a more generic class. commit 9c4b885ee8ef585392d142d97541875f147aec71 Author: Nico Kruber <n...@data-artisans.com> Date: 2017-01-06T17:42:58Z [docs] update some config options to the new, non-deprecated ones commit d21315eefa3d9926bc46d445e9b519fca7cd752b Author: Nico Kruber <n...@data-artisans.com> Date: 2017-01-06T17:14:44Z [FLINK-5178] also use a distributed FS in non-HA mode (if configured) If `high-availability.storageDir` is set and the file system beneath is accessible, it will be used despite the `high-availability` mode setting.
