Basically trying to create a Hue dashboard so i am trying to create index
as per below cloudera exercise 4
http://www.cloudera.com/developers/get-started-with-hadoop-tutorial/exercise-4.html
Hence Below commands ran as expected in CDH 5.5
solrctl --zk quickstart:2181/solr instancedir --generate solr_configs
solrctl --zk quickstart:2181/solr instancedir --create live_logs ./solr_configs
But while below command to create collection
solrctl --zk quickstart:2181/solr collection --create live_logs -s 1
I got below exception
Error CREATEing SolrCore 'live_logs': Unable to create core [live_logs] Caused by: Permission denied: user=solr, access=WRITE, inode="/solr":hdfs:supergroup:drwxr-xr-x at org.apache.hadoop.hdfs.server.namenode.DefaultAuthorizationProvider.checkFsPermission(DefaultAuthorizationProvider.java:257) at org.apache.hadoop.hdfs.server.namenode.DefaultAuthorizationProvider.check(DefaultAuthorizationProvider.java:238) at org.apache.hadoop.hdfs.server.namenode.DefaultAuthorizationProvider.check(DefaultAuthorizationProvider.java:216) at org.apache.hadoop.hdfs.server.namenode.DefaultAuthorizationProvider.checkPermission(DefaultAuthorizationProvider.java:145) at org.apache.hadoop.hdfs.server.namenode.FSPermissionChecker.checkPermission(FSPermissionChecker.java:138) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.checkPermission(FSNamesystem.java:6609) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.checkPermission(FSNamesystem.java:6591) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.checkAncestorAccess(FSNamesystem.java:6543) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.mkdirsInternal(FSNamesystem.java:4331) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.mkdirsInt(FSNamesystem.java:4301) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.mkdirs(FSNamesystem.java:4274) at org.apache.hadoop.hdfs.server.namenode.NameNodeRpcServer.mkdirs(NameNodeRpcServer.java:866) at org.apache.hadoop.hdfs.server.namenode.AuthorizationProviderProxyClientProtocol.mkdirs(AuthorizationProviderProxyClientProtocol.java:321) at org.apache.hadoop.hdfs.protocolPB.ClientNamenodeProtocolServerSideTranslatorPB.mkdirs(ClientNamenodeProtocolServerSideTranslatorPB.java:601) at org.apache.hadoop.hdfs.protocol.proto.ClientNamenodeProtocolProtos$ClientNamenodeProtocol$2.callBlockingMethod(ClientNamenodeProtocolProtos.java) at org.apache.hadoop.ipc.ProtobufRpcEngine$Server$ProtoBufRpcInvoker.call(ProtobufRpcEngine.java:617) at org.apache.hadoop.ipc.RPC$Server.call(RPC.java:1060) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:2086) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:2082) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:415) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1671) at org.apache.hadoop.ipc.Server$Handler.run(Server.java:2080)
I tried to gave permissions to user solr by issuing below command
sudo -u hdfs hdfs dfs -chmod 775 /
sudo -u hdfs hdfs dfs -mkdir /user
sudo -u hdfs hdfs dfs -chown solr:solr /user
sudo -u hdfs hdfs dfs -mkdir /tmp
sudo -u hdfs hdfs dfs -chown solr:solr /tmp
But no success as of now i am still no able to create collection because of above error of
<<QUOTE>>
Permission denied: user=solr, access=WRITE

The error is reporting a problem when trying to write into the "/solr" directory, as indicated here:
Unable to create core [live_logs] Caused by: Permission denied: user=solr, access=WRITE, inode="/solr":hdfs:supergroup:drwxr-xr-x at
You need to give the solr user ownership of the "/solr" directory in hdfs.
sudo -u hdfs hdfs dfs -chown solr:solr /solr
Additionally, you hvae changed permissions/ownership on the /user folder and /tmp, which is not recommended:
sudo -u hdfs hdfs dfs -chown solr:solr /user
sudo -u hdfs hdfs dfs -mkdir /tmp
sudo -u hdfs hdfs dfs -chown solr:solr /tmp
