hdp-3.0.1 --> hive doesn't honor an s3a endpoints if its not AWS.

sahiljankaw — Mon, 08 Oct 2018 15:14:57 GMT

Using a non AWS endpoints for S3a and thereby have a basic issue that hive is not honoring the s3a endpoint if its not AWS. While distcp, hadoop fs, Spark, MapReduce jobs are finding my s3a endpoint and got completed/ successful without any issues but HIVE is ignoring it and is expecting for AWS S3 credentials, as seen in the below example.

I tried three options and error was same with all the 3 options as shown below:

ERROR : FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. java.net.SocketTimeoutException: doesBucketExist on s3aTestBucket: com.amazonaws.AmazonClientException: No AWS Credentials provided by BasicAWSCredentialsProvider EnvironmentVariableCredentialsProvider InstanceProfileCredentialsProvider : com.amazonaws.SdkClientException: Unable to load credentials from service endpoint

Option 1: Ran the create database command as shown above but passing my s3 credentials using JCEKS in the HDFS core-site.xml as
hadoop.security.credential.provider.path=jceks://hdfs@nile3-vm6.centera.lab.emc.com:8020/user/test/s3a.jceks

Option 2: Passing User:s3-Key in URL while creating a databaseI am even tried the option of using CREATE DATABASE IF NOT EXISTS table1 LOCATION 's3a://s3-user:s3-secret-key@s3aTestBucket/user/table1'; but didn't work

Option 3: Even added the below propert on hive-site
hive.security.authorization.sqlstd.confwhitelist.append=hive\.mapred\.supports\.subdirectories|fs\.s3a\.access\.key|fs\.s3a\.secret\.key

On hive shell from Ambari ran the following
set fs.s3a.access.key= s3-access-key;
set fs.s3a.secret.key= s3-secret-key;
CREATE DATABASE IF NOT EXISTS table1 LOCATION 's3a://s3aTestBucket/user/table1';

I saw a similar post from past but not sure if the issue is solved or not

Above issue is observed cause of https://issues.apache.org/jira/browse/HIVE-20386. Refer bug for more details.

As a workaround you can try below methods :

Method 1 : Set below config in core-site.xml

fs.s3a.bucket.<bucket_name>.security.credential.provider.path = <jceks_file_path>

#Replace <bucket_name> and <jceks_file_path> accordingly.

Method 2 : Set below configs in core-site.xml

fs.s3a.bucket.<bucket_name>.access.key = <s3a access key>
fs.s3a.bucket.<bucket_name>.secret.key = <s3a secret key>

#Replace <bucket_name> accordingly.

Let us know if the resolution works.

sahiljankaw — Mon, 08 Oct 2018 22:38:31 GMT

@Soumitra Sulav I tried Method1: i.e added
fs.s3a.bucket.s3aTestBucket.security.credential.provider.path=jceks://hdfs@nile3-vm6.centra.lab.test.com:8020/user/test/s3a.jceks
restarted HDFS on Ambari but seems like it didn't work. Any suggestion? Please find the logs below.

Didn't try Method2 as it can expose my credentials on Ambari UI

ssulav — Tue, 09 Oct 2018 14:26:29 GMT

I believe you are following proper commands to create the jceks file :

hadoop credential create fs.s3a.access.key -value <ACCESS_KEY> -provider jceks://hdfs@<namenode>/tmp/s3a.jceks
hadoop credential create fs.s3a.secret.key -value <SECRET_KEY> -provider jceks://hdfs@<namenode>/tmp/s3a.jceks
#Verify by running below command
hadoop credential list -provider jceks://hdfs@<namenode>/tmp/s3a.jceks

Make sure the hive user can access the jceks file. [Check permissions and owners]

And then you are adding the mentioned configuration in Ambari UI > HDFS > Configs > Custom core-site

I was able to run hive jobs with same scenarios as yours [underlying storage was not AWS]

If still it doesn't work can you try once the Method 2. Just to make sure there isn't any other issue.

@Soumitra Sulav Tried both Methods #1 and #2 today and have attached the logs below. Logs are same for both the methods. Now it seems like its not complaining about AWS but still its failing.

I verified the JCEKS operation by simply running a -ls command with the user and even what you have suggested above comment and it worked. Just to add the cluster is kerberized.

Can you please provide the complete stacktrace.

If you aren't sure where to find the logs refer link

The exception encountered by you has been reported in a secure cluster as yours.

@Soumitra Sulav

While getting logs from YARN resource manager on Web UI at 8088 port in a kerberized cluster, its failing with the authentication error (HTTP Error Code 401, Unauthorized access). I am using chrome and not sure how do I make my web UI to validate the kerberos ticket. Any suggestions.

Re: hdp-3.0.1 --> hive doesn't honor an s3a endpoints if its not AWS.

ssulav — Tue, 23 Oct 2018 14:42:38 GMT

@Sahil Kaw You can follow these steps to get logs from UI :

https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.5/bk_security/content/enabling_browser_access_spnego_web_ui.html

OR easier way is to get it from the node/servers.

Just goto /var/log/hadoop-yarn/yarn/yarn*resourcemanager*log

Above file will be log rotated. You can find the relevant file which contains the error stack trace.

@Soumitra Sulav Today I redeployed my HDP cluster and it seems to be working with both the methods that you have shared above. I am not sure why it wasn't working with previous set up and seems like as an intermittent issue. I would keep you posted incase I find it again. Thanks for all your help in this.
