what is the range of spark version that CDH6.3.x supported?
does CDH6.3.x support spark3.x?
Spark1.6/2.3 arent available in CDH6.3 - Unlike CDH5 you cant add another spark version in CDH6
Quote from doc:
Important: CDH 6 does not support using multiple versions of Spark. Upgrading to CDH 6 disables the CDS 2 parcel if it exists, and all Spark services will use the built-in Spark version
thank you，now i know that CDH6.3.x is only support one spark。
my second question is：can i replace the build-in spark，for example，CDH6.3.3 's build-in spark version is 2.4.0, can i replace it to spark3.0 or spark 2.0
does CDH6.3 supported spark2 - 3 ???
Having the possibility to have different builds of Apache Spark in 6.x is an interesting question, however, the Apache Spark versions also should be compatible with 6.x.
The Apache Spark 2.2 and 2.3 are not compatible with 2.4.x, so this means the platform supporting 2.4.x may not work with 2.2.x. On the other hand, Apache Spark 3.x is on Scala 2.12 only, so I am interested to know if this possible on 6.x at all.
