hadoop - Does webhdfs support high availability when failover happens -


iam using hadoop 2.7.1 on centos 7

when high availability included hadoop cluster

and active name node fails ,it becomes stand by

but webhdfs doesn't support high availability ?isn't

what should alternative send , put request other active name

node failure of master name node

yes, webhdfs not high availability aware. issue still open. refer hdfs-6371

instead, can opt httpfs. inteoperable webhdfs rest api , ha aware.

or, write custom implementation redirect requests active namenode.
