upgrade CDH 5.5

[#1]

I want to upgrade from CDH 5.2.1 to CDH 5.5

I was using package but I wanted to use parcel for the upgrade.

I upgrade Cloudera Manager 5.5.3 then now I try to upgrade CDH.

The problem come from I upgrade Spark before :

•  spark 1.2.0+cdh5.3.1+365 1.cdh5.3.1.p0.17 CDH 5.3.1

Now i got error :

• Detected multiple CDH versions : [CDH 5.3.1, CDH 5.2.1]

Should I downgrade Spark first ? how can I do this.

Or maybe delete spark, upgrade then reinstall spark ?
