So I have been doing some testing today and I noticed that once I disable impersonation I am able to run queries in hue via the impala editor (not sure if ldap is in action here) BUT I am unable to access impala via the command line.

@Iron   I don't think it is mandatory to enable the safemode during copyToLocal. May be you can use safemode to make sure nobody is updating/deleting/inserting the data during the data copy.   I know the difficulties without cloudera manager/hortonworks, etc   Long back, i've used the below export/import method for Hive table backup, again this will export the data to HDFS and you still have to use copyTolocal.

below is the example let me know if that works for you.    You can use Range or hash partition , also we can perform Range as well as hash partition together or just hash partition by using bucket .    Below is the table that has primary key that coloum id we are using for partition (that is a good practice )    CREATE TABLE customersDetails ( state STRING, PRIMARY KEY (state, name) ) PARTITION BY RANGE (state) ( PARTITION VALUE = 'al', PARTITION VALUE = 'ak', PARTITION VALUE = 'wv', PARTITION VALUE = 'wy' ) STORED AS KUDU;   ...

@HarshJ Thanks for inputs. I checked heap charts on jobtracker instance and it's hitting the maximum heap value frequently and then reducing to little less value. Also, there has not been any change/increase in load. I checked the jobtracker logs but couldn't find any pauses as logging is not enabled for GC. Can you please let me know what are the history retention configurations of jobtracker? Can you please suggest me how to identify the reason behind the GC taking significant time? Thanks, Priya ...
