Kudu cluster - connection error

We are trying to set up a three node kudu cluster as part of a POC. Our nodes are have additional ppk-layer of authentication. We have manually installed hdfs,yarn and impala successfully and are working fine. We have 3 kudu masters- one on each node - and 3 kudu tservers - one on each node. 

 

Contents of config files are :

 

/etc/default/kudu-master

export FLAGS_log_dir=/testpoc/hadoop_logs/kudu
export FLAGS_rpc_bind_addresses=0.0.0.0:7051

 

/etc/default/kudu-tserver

export FLAGS_log_dir=/testpoc/hadoop_logs/kudu
export FLAGS_rpc_bind_addresses=0.0.0.0:7050

 

 

/etc/kudu/conf/master.gflagfile

# Do not modify these two lines. If you wish to change these variables,
# modify them in /etc/default/kudu-master.
--fromenv=rpc_bind_addresses
--fromenv=log_dir
--master_addresses=***.**.**.**,***.**.**.**,***.**.**.**

--fs_wal_dir=/testpoc/kudu/master
--fs_data_dirs=/testpoc/kudu/master

 

 

/etc/kudu/conf/tserver.gflagfile

# Do not modify these two lines. If you wish to change these variables,
# modify them in /etc/default/kudu-tserver.
--fromenv=rpc_bind_addresses
--fromenv=log_dir
--master_addresses=***.**.**.**,***.**.**.**,***.**.**.**

--fs_wal_dir=/testpoc/kudu/tserver
--fs_data_dirs=/testpoc/kudu/tserver
--tserver_master_addrs=***.**.**.**,***.**.**.**,***.**.**.**

 

/etc/default/impala

IMPALA_CATALOG_SERVICE_HOST=***.**.**.**
IMPALA_STATE_STORE_HOST=***.**.**.**
IMPALA_STATE_STORE_PORT=24000
IMPALA_BACKEND_PORT=22000
IMPALA_LOG_DIR=/testpoc/hadoop_logs/impala
IMPALA_SCRATCH_DIR=/testpoc/impala_scratch_dir
KUDU_MASTER_HOSTS=***.**.**.**,***.**.**.**,***.**.**.**

IMPALA_CATALOG_ARGS=" -log_dir=${IMPALA_LOG_DIR} "
IMPALA_STATE_STORE_ARGS=" -log_dir=${IMPALA_LOG_DIR} -state_store_port=${IMPALA_STATE_STORE_PORT}"

-be_port=${IMPALA_BACKEND_PORT} \

ENABLE_CORE_DUMPS=false

 

 

kudu-master.ERROR

If we try to create a kudu table using impala shell, we get the following error:

Are we missing something here? Let us know if more info is required.

Any kind of help is appreciated. Thanks.

Re: Kudu cluster - connection error

Seems it was ntp issue. Although, we did not see any clock synchronization related error.
