Problem was solved by: Cloudera Manager -> HDFS -> Configuration Than in the "Cluster-wide Advanced Configuration Snippet (Safety Valve) for core-site.xml" add: <property> <name>hadoop.proxyuser.sdc.hosts</name> <value>*</value> </property> <property> <name>hadoop.proxyuser.sdc.groups</name> <value>*</value> </property> Then restart the cluster

We have StramSets (STS) intalled using Clodera parcels on CDH 5.6.0. A pipeline is generating test and trying to save to HDFS. Kereberos is enabled. Keytab file is in the Configuration Directory. But I get the following error: HADOOPFS_44 - Could not verify the base directory: 'org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): User: sdc/<HOST>.lab.nordigy.ru@LAB.NORDIGY.RU is not allowed to impersonate devuser@LAB.NORDIGY.RU' Any one have an idea?

I am trying the sample impyla code from http://blog.cloudera.com/blog/2014/04/a-new-python-client-for-impala/ And getting "impala.error.HiveServer2Error: Failed after retrying 3 times" impyla is installed on the hadoop (CDH-5.3.2) node I log in to Tried: from impala.dbapi import connect conn = connect(host='my.impala.host', port=21050) cursor = conn.cursor() cursor.execute('SELECT * FROM youval_db.accounts_info LIMIT 10') print cursor.description # prints the result set's schema results = cursor.fetchall() Where for "my.impala.host" I used the the impala host I got from the cloudera manager. (tried with host from the following groups: Impala Catalog Server Default Group, Impala Daemon Default Group and Impala StateStore Default Group) got the same error for All. Also tried with conn = connect() It did not work as well. Any suggestion on how to make it work? Thanks
