Thanks Robert for your inputs. I added the property jce.name in the ambari.properties file and restarted the ambari-server. After that the dekerberize options went through till the point that now it fails at the step "start services". From the error logs it indicates the following: File "/usr/lib/python2.6/site-packages/resource_management/core/shell.py", line 291, in _call raise Fail(err_msg) resource_management.core.exceptions.Fail: Execution of 'cat /var/lib/ambari-agent/tmp/pass | ACCUMULO_CONF_DIR=/usr/hdp/current/accumulo-tracer/conf/server /usr/hdp/current/accumulo-client/bin/accumulo shell -u root -f /var/lib/ambari-agent/tmp/cmds' returned 1.

I ran the bootstrap_config.sh file and chose the following options but it now fails indicating that JAVA_HOME is not set. I set the JAVA_HOME globally and in the accumulo-env.sh file. Still the error prevails. Can you please let me know if i am doing it right. Thanks ... View more

Kuldeep, I ran the above CURL command on the host running the ambari-server and then tried to disable kerberos from ambari UI. The stop services step failed on all hosts. The stderr file has the following error: Traceback (most recent call last): File "/var/lib/ambari-agent/cache/common-services/KERBEROS/1.10.3-10/package/scripts/kerberos_client.py", line 77, in <module> KerberosClient().execute() File "/usr/lib/python2.6/site-packages/resource_management/libraries/script/script.py", line 219, in execute method(env) File "/var/lib/ambari-agent/cache/common-services/KERBEROS/1.10.3-10/package/scripts/kerberos_client.py", line 31, in install self.configure(env) File "/var/lib/ambari-agent/cache/common-services/KERBEROS/1.10.3-10/package/scripts/kerberos_client.py", line 40, in configure self.setup_jce() File "/var/lib/ambari-agent/cache/common-services/KERBEROS/1.10.3-10/package/scripts/kerberos_common.py", line 448, in setup_jce raise Fail("Security is enabled, but JCE policy zip is not specified.") resource_management.core.exceptions.Fail: Security is enabled, but JCE policy zip is not specified. ...
