> When deploying a cluster with Hive (1.2.1000, in this case), Ambari issues an incorrect WebHDFS request:
> {code}
> 2017-11-20 20:21:21,839 - call['ambari-sudo.sh su hdfs -l -s /bin/bash -c 'curl -sS -L -w '"'"'%{http_code}'"'"' -X GET '"'"'http://dtucker-rjy277d.west.isilon.com:8082/webhdfs/v1?op=GETFILESTATUS&user.name=hdfs'"'"' 1>/tmp/tmpzipnFe 2>/tmp/tmpbGajx_''] {'logoutput': None, 'quiet': False}
> {code}
> That command should be:

> curl -sS -L -w '%{http_code}' -X GET 'http://dtucker-rjy277d.west.isilon.com:8082/webhdfs/v1/?op=GETFILESTATUS&user.name=hdfs'
> {code}
> (Note the / after v1.)
> On Apache, this results in a FileNotFoundException (404); however, this causes problems with OneFS which returns an IllegalArgumentException (400) and prevents the Metastore from starting.
