Borislav Iordanov commented on HADOOP-16524:
--------------------------------------------
Hi all,
First time contributor here. It appears this is still an open issue and I hope
you don't mind me taking a stab at it. Could anyone take a look at the
following PR - [https://github.com/apache/hadoop/pull/2470] - and let me know
what you think? The implementation also covers reloading the keystore in
DataNode and it introduces a new configuration parameter that governs the
polling interval. I've tried to follow the existing ReloadingX509TrustManager
closely, but to avoid code duplication and to reduce the number of extra
threads spun, I've consolidated the polling in a standard java.util.Timer.
Otherwise, I've tried to follow the contributor coding guidelines, hope I did a
good job there. Please let me know if I've missed something with respect to the
process etc.
Best, Boris
