There are datasource for Cassandra and hbase, however I am not sure how useful they are, because then you need to do also implement the logic of opentsdb or kairosdb.
Better to implement your own data sources. Then, there are several projects enabling timeseries queries in Spark, but I am not sure how much they are used. Additionally time series analysis may imply a lot of different functionality (eg matching time stamps), which those they may not have. > On 21.
