AW: Migration of Hadoop Warehouse to newer versions lead to bad performance for JDBC-data-retrieval

ve an OLAP tool which retrieves the data through JDBC. This has been working reliably for years on the old infrastructure, the poor performance with the new cluster block the migration to the new cluster. Thanks, Julien Julien Tane Big Data Engineer [Tel.] +49 721 98993-393 [Fax] +49 72

Migration of Hadoop Warehouse to newer versions lead to bad performance for JDBC-data-retrieval

4) What are the parameters and settings we could use to make sure the data-retrieval-performance is (as) high (as possible)? q5) Could the garbage collector be slowing down the data-retrieval to this extent? How can we find out? Looking forward to your ideas, Julien Tane Julien Tane Big Data
