@srowen will this pr be meged into branch-2.0? |
|
I'll wait a moment to see if @JoshRosen has concerns about it. The original change was approved, for branch 1.6, but in re-reading, I wonder if it was only accidentally discussed as 1.6-only. |

@JoshRosen can you have a look at this pr? |

This is a pull request that was originally merged against branch-1.6 as #12000, now being merged into master as well. srowen zzcclp JoshRosen This pull request fixes an issue in which cluster-mode executors fail to properly register a JDBC driver when the driver is provided in a jar by the user, but the driver class name is derived from a JDBC URL (rather than specified by the user). The consequence of this is that all JDBC accesses under the described circumstances fail with an IllegalStateException. I reported the issue here: https://issues.apache.org/jira/browse/SPARK-14204 My proposed solution is to have the executors register the JDBC driver class under all circumstances, not only when the driver is specified by the user. This patch was tested manually. I built an assembly jar, deployed it to a cluster, and confirmed that the problem was fixed. Author: Kevin McHale <kevin@premise.com> Closes #14420 from mchalek/mchalek-jdbc_driver_registration. (cherry picked from commit 685b08e) Signed-off-by: Sean Owen <sowen@cloudera.com>
