If all sql results have same set of columns you could UNION all the dataframes
Create an empty df and Union all
Then reassign new df to original df before next union all
Not sure if it is a good idea, but it works

Hi,
Please bear me for asking such a naive question
I have list of conditions (dynamic sqls) sitting in hbase table .
I need to iterate through those dynamic sqls and add the data to dataframes.
As we know dataframes are immutable ,when I try to iterate in for loop as shown
below I get only last dynamic sql result set .
var dffiltered : DataFrame = sqlContext.emptyDataFrame
for ( i <- 0 to (dfFilterSQLs.length - 1)) {
println("Condition============="+dfFilterSQLs(i))
dffiltered =
dfresult.filter(dfFilterSQLs(i)).select("Col1","Col2","Col3","Col4","Col5")
dffiltered.show
}
How can I keep on appending data to dataframe and get the final result having
all the sql conditions.
Thanks in advance for the help.
Thanks,
Divya
