Hi Team,

Trying to follow the Tutorial in Cloudera Search deployment for CDH 6.2

Everything works until this command:

solrctl collection --create test_collection -s 2 -c test_collection_config

we get the exception:

{ "responseHeader":{ "status":0, "QTime":33610}, "failure":{ "gis18.example.com:8983_solr":"org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException:Error from server at http://gis18.example.com:8983/solr: Error CREATEing SolrCore 'test_collection_shard1_replica_n1': Unable to create core [test_collection_shard1_replica_n1] Caused by: Permission denied: user=solr, access=WRITE, inode=\"/\":root:supergroup:drwxr-xr-x\n\tat org.apache.hadoop.hdfs.server.namenode.FSPermissionChecker.check(FSPermissionChecker.java:400)\n\tat org.apache.hadoop.hdfs.server.namenode.FSPermissionChecker.checkPermission(FSPermissionChecker.java:256)\n\tat org.apache.hadoop.hdfs.server.namenode.FSPermissionChecker.checkPermission(FSPermissionChecker.java:194)\n\tat org.apache.hadoop.hdfs.server.namenode.FSDirectory.checkPermission(FSDirectory.java:1855)\n\tat org.apache.hadoop.hdfs.server.namenode.FSDirectory.checkPermission(FSDirectory.java:1839)\n\tat org.apache.hadoop.hdfs.server.namenode.FSDirectory.checkAncestorAccess(FSDirectory.java:1798)\n\tat org.apache.hadoop.hdfs.server.namenode.FSDirMkdirOp.mkdirs(FSDirMkdirOp.java:60)\n\tat org.apache.hadoop.hdfs.server.namenode.FSNamesystem.mkdirs(FSNamesystem.java:3101)\n\tat org.apache.hadoop.hdfs.server.namenode.NameNodeRpcServer.mkdirs(NameNodeRpcServer.java:1123)\n\tat org.apache.hadoop.hdfs.protocolPB.ClientNamenodeProtocolServerSideTranslatorPB.mkdirs(ClientNamenodeProtocolServerSideTranslatorPB.java:696)\n\tat org.apache.hadoop.hdfs.protocol.proto.ClientNamenodeProtocolProtos$ClientNamenodeProtocol$2.callBlockingMethod(ClientNamenodeProtocolProtos.java)\n\tat org.apache.hadoop.ipc.ProtobufRpcEngine$Server$ProtoBufRpcInvoker.call(ProtobufRpcEngine.java:523)\n\tat org.apache.hadoop.ipc.RPC$Server.call(RPC.java:991)\n\tat org.apache.hadoop.ipc.Server$RpcCall.run(Server.java:869)\n\tat org.apache.hadoop.ipc.Server$RpcCall.run(Server.java:815)\n\tat java.security.AccessController.doPrivileged(Native Method)\n\tat javax.security.auth.Subject.doAs(Subject.java:422)\n\tat org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1875)\n\tat org.apache.hadoop.ipc.Server$Handler.run(Server.java:2675)\n",

Please check if userid 'solr' is the member of "supergroup"; If not add solr into supergroup.
