Class_cast_exception for index pattern that is created based on two index

[sjain135 (Saurabh)]

I have created the index pattern as df3df2* on two index(df3df2_snap and df3df2_raw). The data type mapping of the fields are String and Float. When I am looking for data of index df3df2*, i am getting error as
