No lease on /tmp/radoop on Cloudera hadoop
Maven
Hi there,
I am new in Rapidminer and hadoop, I just setup a Cloudera hadoop, Rapidminer server and studio on same machine, when loading data into Hadoop we always hit this error connection time out and i checked the hadoop log file, I notice there is one like saying
1. WARN org.apache.hadoop.security.UserGroupInformation: PriviledgedActionException as:XXXXX (auth:SIMPLE) cause:org.apache.hadoop.hdfs.server.namenode.LeaseExpiredException: No lease on /tmp/radoop/197b4c84c4c62eb1c51f11f85f7c6a1f/import_data_integration/00050 (inode 0): File does not exist. Holder DFSClient_NONMAPREDUCE_-1897690113_59 does not have any open files.
2. INFO org.apache.hadoop.ipc.Server: IPC Server handler 3 on 8020, call org.apache.hadoop.hdfs.protocol.ClientProtocol.abandonBlock from 14.192.214.29:2893 Call#34 Retry#0: org.apache.hadoop.hdfs.server.namenode.LeaseExpiredException: No lease on /tmp/radoop/197b4c84c4c62eb1c51f11f85f7c6a1f/import_data_integration/00050 (inode 0): File does not exist. Holder DFSClient_NONMAPREDUCE_-1897690113_59 does not have any open files.
I already given full permission on the folder but the outcome still the same. Anyone has the same problem before?
Thanks! :-[

i would recommend to ask for radoop support on our professional support system at support.rapidminer.com. Since you have a radoop licence you (most likely) will have professional support included.
Quick question: Did you use the virtual machine provided by cloudera? This sandbox thingy?
