Hello @Erik Nor, Thanks, do you know where is the easiest way to create cluster users (rather than via shell), for hive, hdfs etc?

wnascimento · ‎07-14-2016

Hello guys, First of all thanks for your help. My Ranger is already configured with Usersync, I can see that users that were created and give them permissions. My biggest question is if the user that i create on Ranger are only internal to Ranger or they can access hdfs, hive, etc...

wnascimento · ‎07-13-2016

Hello, I need to know if there is a way to create a hdfs/hadoop or hive user via Ranger, not via shell. I can provide or deny access to hdfs folders or files, hive tables or columns, but to the users that already exists. Does anyone knows how I can do it?

Hello @Artem Ervits To read data from WebHcat do I have to put the data inside HDFS? Is there a way to read this data directly via Rest API? I mean, the data of the table, not the metadata. Thank you so much

Hello guys, This is exaclty what I need, query a Hive Table and show results on screen, is it already implemented? Thank you

Hello everyone, I already use HDP in large scale, but I need to know what tool people are using to do Predictive Analysis. I know that are a lot of tools in the market, but I am looking for something that allows me not to have a specific person with a lot of Data Science knowledge, statistics, etc...But i want my business user to build his own analysis. I know that are some tools in the market that aren´t Open Source like SAP Predictive Analysis that has this purpose. Does anyone knows another software like this? Thank you

Hello, It worked fine now, the first solution worked connected to the database, but when Sqoop was running Map Reduce, the same error occurred. This way all Map Reduce agents have this configuration. So the solution is configure the TrustStore parameter on Map Reduce Configuration inside Ambari The value: -Djavax.net.ssl.trustStore=/home/user/truststore.jks Thank you

Hello, Now the problem is the following error: Error: java.lang.RuntimeException: java.lang.RuntimeException: org.teiid.jdbc.TeiidSQLException: TEIID20020 Error establishing socket to host and port: xxxx.hostname:port.

Thanks

Hello Jitendra Yadav The solution was great, the first one (export... HADOOP_OPTS...) worked for me! Thanks

Hello, I am trying to access a VIrtual Database from JBoss Data Virtualization using Sqoop. This database is defined to connect using a Truststore (JKS format), using another application like Squirrel i can connect using the following argument: -Djavax.net.ssl.trustStore=/home/user/truststore-xxxxx.jks Does anyone knows how can I use this argument with Sqoop? Ps.: I already deploy my .jar file on $SQOOP_HOME/lib.

Hello Ryan, Great, unfornately, even after register, the Page Is Not Found. As I am seeing, this is a PDF, the calculator i am talking about was a web page that i put all my requirements and i gives my cluster sizing.

wnascimento · ‎06-03-2016

Hello everyone, Some months ago i used a cluster sizing calculator of Hortonworks, this link was: http://br.hortonworks.com/cluster-sizing-guide/ But now the page is not found, does someone knows if the calculator does not exists anymore? Thanks
