Hello,
I am reading around 1000 input files from disk in an RDD and generating
parquet. It always produces same number of parquet files as number of input
files. I tried to merge them using
rdd.coalesce(n) and/or rdd.repatition(n).
also tried using:
int MB_128 = 128*1024*1024;
sc.hadoopConfiguration().setInt("dfs.blocksize", MB_128);
sc.hadoopConfiguration().setInt("parquet.block.size", MB_128);
No luck.
Is there a way to control the size/number of parquet files generated?
Thanks
Tridib
