Yes I noticed. My question has been in moderation for about 10 days. Can I write an email directly to you if the same problem arise in the future?

Hello, since last week when I try to query cosmos cluster with hive I'll get this error.

hive> select * from muv_tweet limit 10;
FAILED: RuntimeException org.apache.hadoop.ipc.RemoteException: org.apache.hadoop.hdfs.server.namenode.SafeModeException: Cannot create directory /tmp/hive-alessio.caiazza/hive_2015-10-12_12-59-27_269_6614332063661032399-1. Name node is in safe mode.
Resources are low on NN. Safe mode must be turned off manually.

It sounds like a cluster problem and not something strictly related to my query.

2015-09-30 09:17:58 +0100 asked a question cosmos: password reset

Hello, how can I reset a password on cosmos.lab.fi-ware.org ?

cosmos-gui gives an error if you register with a password containig symbols.

Error: internal error creating the account

Subsequnt attempts to register trough the web interface will warn that the user already exists, but ssh access will not work.
