Yes, Agreed - I will involve my DB team to answer this.
We tried pushing MSSQL and Mysql to the max and decided to go with Spark in
2014.
We are happy with Spark but not satisfied with as Mysql . We feel the
bottleneck is at JDBC connector, hence the query.

Anbu,
JDBC is primarily meant for SQL databases (without getting too much
technical). BigData/NoSQL systems like Hive or HBase, that provide a JDBC

Dear Fellow Members,
We have a large data set analytics platform and we have been
looking for an excellent Java developer/ Architect
who could resolve the limitation of JDBC (I doubt if it is a limitation
workingJDBC or the way we look at it).
Here is the short summary, if you are interested we could discuss
in detail.
Bigdata / Large data systems (Hadoop/NOSQL) supports JDBC and not
Ibatis/Mybatis connections.
We see bottle neck on this area when platform is communicating with
Backend. Data is in terabytes.
What is the recommended architecture.
Seeking support from Java experts and developers who has worked on
aton the connectivity, apart
from that we are also looking for good Java developers.
Any help/support appreciated.
Thanks,
anbu.

This started happening to me immediately after I upgraded to Fedora 25.
