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
