@Slim Thanks for your advise. You are right. The NPE is a side effect of running out of memory. It works perfectly (response under 1s with cached data) after reducing Druid Historical buffer size.

Hi, Follow the Hortonworks blog and this instruction, I successfully created my Hive table cube index in Druid and ran some simple queries. But I got a deserialization error when running query Q4.2.

Hi, I was able to deploy a simple word count application on SAM and integrate with Schema Registry, which I really liked. However, soon after the deploy finished, my Storm supervisors halted with the below error.

@dbains, @mthiele, @Daniel Kozlowski, Thank you. It works when created as kafka user. To summarize all the steps -- from Ambari configs, to creating topic, granting permission and testing on kafka console producer/consumer scripts, I created this article Step by Step Recipe for Securing Kafka with Kerberos. Hope it saves others' time 🙂

I found it is a little tricky to get started with a Kerberos enabled Kafka cluster. I created this step by step recipe for securing Kafka with Kerberos, sending and receiving data on console. This is tested on HDP2.5.0 and Ambari 2.4.1. Enabled Kerberos using the Ambari Kerberos setup wizard under Admin -- Kerberos menu. On Ambari Kafka Config UI, change "listeners" property to "PLAINTEXTSASL://localhost:6667". Restart Kafka as requested by Ambari. Create a test topic in Kafka. Must use the kafka service user to do this. $ cd /usr/hdp/current/kafka-broker/bin
$ sudo su kafka
$ kinit -k -t /etc/security/keytabs/kafka.service.keytab kafka/ip-10-0-1-130.ap-northeast-1.compute.internal
$ ./kafka-topics.sh --zookeeper ip-10-0-1-130.ap-northeast-1.compute.internal:2181 --create --topic foo --partitions 1 --replication-factor 1
Created topic "bar".
Grant permission to user. This can be done using Kafka native ACL mechanism or Apache Ranger. In the example, we use Kafka ACL. User bob needs to be existing in KDC. # Grant user bob as producer on topic foo
./kafka-acls.sh --authorizer-properties zookeeper.connect=ip-10-0-1-130.ap-northeast-1.compute.internal:2181 \
--add --allow-principal User:bob \
--producer --topic foo
Adding ACLs for resource `Topic:foo`:
User:bob has Allow permission for operations: Describe from hosts: *
User:bob has Allow permission for operations: Write from hosts: *
Adding ACLs for resource `Cluster:kafka-cluster`:
User:bob has Allow permission for operations: Create from hosts: *
Current ACLs for resource `Topic:foo`:
User:bob has Allow permission for operations: Describe from hosts: *
User:bob has Allow permission for operations: Write from hosts: *
# Grant user bob as consumer
./kafka-acls.sh --authorizer-properties zookeeper.connect=ip-10-0-1-130.ap-northeast-1.compute.internal:2181 \
--add --allow-principal User:bob \
--consumer --topic foo --group *
Adding ACLs for resource `Topic:foo`:
User:bob has Allow permission for operations: Read from hosts: *
User:bob has Allow permission for operations: Describe from hosts: *
Adding ACLs for resource `Group:connect-distributed.sh`:
User:bob has Allow permission for operations: Read from hosts: *
Current ACLs for resource `Topic:foo`:
User:bob has Allow permission for operations: Read from hosts: *
User:bob has Allow permission for operations: Describe from hosts: *
User:bob has Allow permission for operations: Write from hosts: *
Current ACLs for resource `Group:connect-distributed.sh`:
User:bob has Allow permission for operations: Read from hosts: *
Confirm the above works using the kafka console producer and consumer scripts. # Switch to bob user and log in to KDC.
$ kinit bob
# Start console producer
$ ./kafka-console-producer.sh --broker-list ip-10-0-1-130.ap-northeast-1.compute.internal:6667 --topic foo --security-protocol PLAINTEXTSASL
# On another terminal, start console consumer
./kafka-console-consumer.sh --zookeeper ip-10-0-1-130.ap-northeast-1.compute.internal:2181 --topic foo --security-protocol PLAINTEXTSASL
{metadata.broker.list=ip-10-0-1-130.ap-northeast-1.compute.internal:6667, request.timeout.ms=30000, client.id=console-consumer-57797, security.protocol=PLAINTEXTSASL}
# Type something on the producer terminal, it should appears on the console terminal immediately.

Hi, After enabled Kerberos using Ambari, I got problem creating topics in Kafka using the kafka-topics.sh script. The topic was created, but its status is wrong without leader. It seems the topic is created with PLAINTEXT, while there is only PLAINTEXTSASL broker in the cluster after enabled Kerberos. The only configuration change I made is to chagne broker listener from 'PLAINTEXT://localhost:6667' to 'PLAINTEXTSASL://localhost:6667'. As posted in this question, I also changed the kafka-topics.sh to make it work with Kerberos. I am using HDP2.5.3. $ ./kafka-topics.sh --zookeeper ip-10-0-0-149.ap-northeast-1.compute.internal --create --partitions 1 --replication-factor 1 --topic mytopic
Created topic "mytopic".
$ ./kafka-topics.sh --zookeeper ip-10-0-0-149.ap-northeast-1.compute.internal --describe --topic mytopic
Topic:mytopic PartitionCount:1 ReplicationFactor:1 Configs:
Topic: mytopic Partition: 0 Leader: none Replicas: 1001 Isr:

Solved by the below workaround. This looks like a bug in kafka-topics.sh. 1. Add KAFKA_CLIENT_KERBEROS_PARAMS before executing actual TopicCommand if running in a Kerberos enabled cluster. $ cat kafka-topics.sh
# check if kafka_jaas.conf in config , only enable client_kerberos_params in secure mode.
KAFKA_HOME="$(dirname $(cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd ))"
KAFKA_JAAS_CONF=$KAFKA_HOME/config/kafka_jaas.conf
if [ -f $KAFKA_JAAS_CONF ]; then
export KAFKA_CLIENT_KERBEROS_PARAMS="-Djava.security.auth.login.config=$KAFKA_HOME/config/kafka_client_jaas.conf"
fi
exec $(dirname $0)/kafka-run-class.sh kafka.admin.TopicCommand "$@"
2. Use Zookeeper server FQDN instead of localhost in command line. $ kinit
$ ./kafka-topics.sh --zookeeper ip-10-0-0-149.ap-northeast-1.compute.internal:2181 --create --topic foo --partitions 1 --replication-factor 1

You can mask a column in Hive using the dynamic column masking feature in Apache Ranger. This is available in HDP2.5 and later. Please see this blog for details. As per HIVE-5207, I don't think Hive natively supports column encrypt. If you want to encrypt all the dataset, one option is to use the HDFS transparent data encryption (TDE) feature. However, this does not apply to selected column. For that, the best solution is to use Hive UDF to plug in encrypt implementation on selected column.

Solved this by setting hadoop.proxyuser.root.hosts=*. For some reason, the HDFS request to create the directory was sent from host where neither Ambari Server nor HS2 is running. Not sure why but change this setting solved the issue.

Do not know how to fix it.. Also checked NN log, no error occurred.

I have same issue on HDP 2.5 & Ambari 2.4.0.1. I have created all the necessary HDFS directories and grant proper permission, but a simple 'show tables' query just doesn't work. Digging into HDFS logs, I found Ambari Hive View didn't create staging directory under /user/admin/hive/jobs. It should create hive-job-6-2016-12-16_06-15 directory before trying to write the hql file. $ tail -f hdfs-audit.log | grep '/user/admin'

I also have another working Ambari Hive View on HDC. It creates the staging directories and hql properly. $ tail -f hdfs-audit.log | grep '/user/admin'
