CDH5 SerDe library 'org.apache.hadoop.hive.contrib.serde2.RegexSerDe' is not supported.

[#1]

Hi Cloudera  People,

I am a beginner in Cloudera. I downloaded the VMQuickstart CDH5  and I try to do the tutorials but I can not finish the tutorial 3 because I have this error when I try to view in  Impala  the table " intermediate_access_logs"

Your query has the following error(s):

AnalysisException: Failed to load metadata for table: default.intermediate_access_logs CAUSED BY: TableLoadingException: Failed to load metadata for table: intermediate_access_logs CAUSED BY: InvalidStorageDescriptorException: Impala does not support tables of this type. REASON: SerDe library 'org.apache.hadoop.hive.contrib.serde2.RegexSerDe' is not supported.

Thansk for helping

The intermediate_access_log table is not intended to be viewed directly,
especially not in Impala. In that tutorial step you're actually using Hive
to do an ETL (extract transform load) job. The Apache logs are in a format
that is hard to query directly through SQL, so we use one of Hive's
extensions to express a regular expression to break up the fields more
explicitly. After this step, the intermediate table is not useful. It's the
second table you create (tokenized_access_logs) that should be queried from
Impala.
