Hi all!
CDH 5.4 is out[1] and we’d like to upgrade. We are doing this now, rather than later, because there is an important Parquet/Hive related bug that has been fixed in this version[2]. This upgrade will include Spark 1.3, which should at least make one researcher happy.
To do this upgrade, I need to schedule some downtime for Hadoop. I’d like to do this on Monday May 4th. I expect the upgrade to take me no more than an hour or two, but just to be safe I’d like to schedule the downtime for the whole day.
If anyone has critical things that they absolutely have to run on Monday, let me know now and I will find another day.
Thanks!
