We were able to install the official parcel. The only problem encountered was that all the signature files in the repository have extension .sha1. Our CM (5.8.3) were expecting .sha . Manually renaming it allowed the install to complete.
How i can know if the parcels files should has sha or sha1 signature?
When Spark2 will be part of CDH4 parcels, which version?
currently i have 1.6, when i add 2.0 will the spark history server be 2.0 also? if i used 2.0 parcels, which one will be the active one on the cluster 1.6 or 2.0?
