@Harshal Joshi You may want to check your Ambari Metric TTL settings and adjust accordingly. https://docs.hortonworks.com/HDPDocuments/Ambari-2.2.1.1/bk_ambari_reference_guide/content/ams_aggregated_ttl_settings.html. Also, this issue was addressed in a previous post. https://community.hortonworks.com/questions/13419/how-can-we-delete-old-data-of-ambari-metric-server.html

@Alex Raj be aware that ACID in Hive is still in tech preview and should not be used in production.

I’m trying to get some twitter JSON to show up in Hive and I’m not having any luck. All I get are NULLS returned and no errors. I've tried the native JSON serde as well as the openx serde but get the same results. LOAD DATA INPATH '/tmp/tweets_staging/‘ OVERWRITE INTO tweets; ADD JAR /hadoop/json-serde-1.3.8-SNAPSHOT-jar-with-dependencies.jar; SELECT * FROM tweets LIMIT 100; tweet-table.txt

Thanks @Artem Ervits but I get the same results from HiveCL. It's all nulls. 9688f87e-f96b-4330-833c-c2e59ab2e9c9.png. Let me try @Michael M suggestion and I'll update the thread with the results.

I created a table based off the Hive native JSON SerDe. My intention is to create a table for tweets. I've attached tweet-table.txt. The table is created without errors. I then load the data using the LOAD DATA INPATH command and I get no errors. When I try to select data from the table, I get the following error: {"message":"H170 Unable to fetch results. java.io.IOException: org.apache.hadoop.hive.serde2.SerDeException: java.io.IOException: Start token not found where expected [ERROR_STATUS]","status":500,"trace":"org.apache.ambari.view.hive.client.HiveErrorStatusException: H170 Unable to fetch results. java.io.IOException: org.apache.hadoop.hive.serde2.SerDeException: java.io.IOException: Start token not found where expected [ERROR_STATUS]\n\norg.apache.ambari.view.hive.client.HiveErrorStatusException: H170 Unable to fetch results. java.io.IOException: org.apache.hadoop.hive.serde2.SerDeException: java.io.IOException: Start token not found where expected [ERROR_STATUS Any suggestions?

@omkar pathallapalli I'm assuming "sample" is a database name. You do not specify the database name after the port number. Here is an example sqoop command that pulls a table from the AdventureWorks database. sqoop import --connect "jdbc:sqlserver://192.168.56.101:1433;database=AdventureWorksDW2014;username=hadoop;password=hadoop" --table DimCustomer --hive-import

We have a large VMware installation and are looking for options to deploy HDP to a private cloud using Cloudbreak. We would like to burst to a private cloud as well as bring up and bring down managed HDP services. Is this possible? I know Cloudbreak works with OpenStack but we are looking specifically for a VMware based solution.
