Impala table creation takes too long

We are creating external Impala table against parquet data. We drop the table if it exists and create a table with the same name. During recreation of the table sometimes it takes hours. Is there something we can do to improve this?

 

We are creating the table using JDBC connection.

Our JDBC string is :- jdbc:impala://ip_of_impala:21050/ooxp;auth=noSasl

 

And we are using com.cloudera.impala.jdbc3.Driver on CDH 5.3 stack.
