Hi Guys,

I am using  CDH 5.7, VirtualBOx QuickStart.

I am trying to get an access to my data through WebHcat. I am trying to open in browser foloriwng uri:

http://localhost:50111/templeton/v1/ddl/database/default/table?user.name=cloudera

As a result I obtain in browser:

{"error":"FAILED: SemanticException Operation not supported.","errorDetail":"org.apache.hadoop.hive.ql.parse.SemanticException: Operation not supported.\n\tat org.apache.hive.hcatalog.cli.SemanticAnalysis.HCatSemanticAnalyzer.preAnalyze(HCatSemanticAnalyzer.java:153)\n\tat org.apache.hadoop.hive.ql.Driver.compile(Driver.java:449)\n\tat org.apache.hadoop.hive.ql.Driver.compile(Driver.java:311)\n\tat org.apache.hadoop.hive.ql.Driver.compileInternal(Driver.java:1194)\n\tat org.apache.hadoop.hive.ql.Driver.runInternal(Driver.java:1289)\n\tat org.apache.hadoop.hive.ql.Driver.run(Driver.java:1120)\n\tat org.apache.hadoop.hive.ql.Driver.run(Driver.java:1108)\n\tat org.apache.hive.hcatalog.cli.HCatDriver.run(HCatDriver.java:43)\n\tat org.apache.hive.hcatalog.cli.HCatCli.processCmd(HCatCli.java:291)\n\tat org.apache.hive.hcatalog.cli.HCatCli.processLine(HCatCli.java:245)\n\tat org.apache.hive.hcatalog.cli.HCatCli.main(HCatCli.java:183)\n\tat sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)\n\tat sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57)\n\tat sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)\n\tat java.lang.reflect.Method.invoke(Method.java:606)\n\tat org.apache.hadoop.util.RunJar.run(RunJar.java:221)\n\tat org.apache.hadoop.util.RunJar.main(RunJar.java:136)\n","errorCode":40000,"sqlState":"42000","database":"default"}

In webhcat.log I found following information:

 WHen I send a following GET: http://localhost:50111/templeton/v1/status, an answer is correct:

{"status":"ok","version":"v1"}

How to deal with such a problem.........
