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.

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.

Is it possible to know the answer to the second question please?
