I install the latest impala(version0.5) with Cloudera Manager 4.1.1
when I start the impala daemon of the impala service, I got the following
error:

The specified datastore driver ("com.mysql.jdbc.Driver") was not found in
the CLASSPATH. Please check your CLASSPATH specification, and the name of
the driver

to see log file in the attached

I have add mysql-connector-java-5.1.23-bin.jar into /usr/lib/hive/lib and
/usr/lib/impala/lib

what is the solution?

    Hi,

    Per Step-4 of https://ccp.cloudera.com/display/ENT41DOC/Installing+Impala+with+Cloudera+Manager,
    you will need to place the MySQL connector jar in the system level
    /usr/share/java path.

    Also, CM 4.1.1. does not support Impala 0.5. Impala is in beta and with
    each release of Impala we add features to it. A corresponding CM release is
    made to support new features. You will need CM 4.1.4 to use Impala 0.5.

    You can look at release notes of CM to figure out which version of Impala
    it supports.
