CDH 5.7.5 compatibility with RHEL 7.5

Hi All,

 

Could someone please highlight the issues that may occur if we have CDH5.7.5 and the RHEL OS is upgraded to 7.5 and above?

 

Thanks

@ca,

 

Since Cloudera has not tested CM/CDH on RHEL 7.5, we cannot certify CM/CDH will work on that OS version.

In general, it is possible, and even likely, that you will not encounter any problems.

 

If you do hit a problem that is related to the later release, they will not fixed.

 

Depending on how much risk you are willing to incur, you could try it.  If you are paying Cloudera for support, consult with your Cloudera Account team.

 

Let us know if you have any questions.

 

Ben

Thanks for the info.

 

So should i expect the same answer if i ask:

why RHEL 7.5 is supported only by CDH 5.11.1 and higher?

 

Thanks

@ca,

 

Testing for compliance and compatibilty takes a good deal of effort so we usually only certifiy later OS release on the latest CM/CDH versions.

 

By "supported" in this case we mean that we have tested and certify CM/CDH on that OS release.

 

Part of obtaining software from our distrobution is that we test to help ensure stability with the products.  That takes some of the guess-work out, but that also means that if you want that assurance, "certified" configurations may not include the latest OS releases and third-party code.

We seek to balance stability with rich features that our users demand.

 

Hope that helps explain things a bit more.  Please feel free to ask more if you have any questions!
