VM cloudera - custom cloudera and permissions?

I downloaded and installed VM Cloudera 4.4 to play with Hadoop. I already have a cluster on the platform for my work, so I know a little how chaos works. Therefore, I think that my problem comes from my misunderstanding of Linux and its users and group.

With a hive:

I am trying to create a hive table with a shell and it works. I have a table in / user / hive / warehouse / test witch owned by user cloudera of cloudera group.

I have some data files (.txt) in hdfs: / user / cloudera (user: cloudera and group: hive) that I upload to my hive table with:

LOAD DATA INPATH '/user/cloudera/*.txt' INTO TABLE test;

This is what I got:

hive> LOAD DATA INPATH '/user/cloudera/jeuDeTest/*.txt' INTO TABLE test;
Loading data to table default.test
chgrp: changing ownership of '/user/hive/warehouse/test/_log24310.txt': User does not belong to hive
chgrp: changing ownership of '/user/hive/warehouse/test/_log24311.txt': User does not belong to hive
Table default.test stats: [num_partitions: 0, num_files: 2, num_rows: 0, total_size: 10161843, raw_data_size: 0]
OK
Time taken: 2.472 seconds

I never had such an error message, but the files were moved. If I try SELECT *, there will be no result.

With HBase:

/user/cloudera/jeuDeTest/*.txt
