Hi Sampath, Flink CLI need to retrieve the JobManager leader address, so it need to access the HA specific configuration. Because if based on Zookeeper to implement the HA, the leader address information will fetch from Zookeeper.
The main use of config item *high-availability.storageDir* is storage (Job graph, checkpoint and so on). Actually, the real data is stored under this path which used to recover purpose, zookeeper just store a state handle. --- Thanks. vino. 2018-07-16 15:28 GMT+08:00 Sampath Bhat <sam414255p...@gmail.com>: > > ---------- Forwarded message ---------- > From: Sampath Bhat <sam414255p...@gmail.com> > Date: Fri, Jul 13, 2018 at 3:18 PM > Subject: Flink CLI properties with HA > To: user <user@flink.apache.org> > > > Hello > > When HA is enabled in the flink cluster and if I've to submit job via > flink CLI then in the flink-conf.yaml of flink CLI should contain this > properties - > high-availability: zookeeper > high-availability.cluster-id: flink > high-availability.zookeeper.path.root: flink > high-availability.storageDir: <some path> > high-availability.zookeeper.quorum: <zookeeper IP:port> > > What is the need of high-availability.storageDir for flink CLI.
