Indefinite pause while trying to insert data into HBase
It seems the problem was nothing to do with good old HBase. The horrible and unexplained pause in inserting data was being caused because I was using the opencsv CSVReader to read a csv file with size>5GB in the insert code.(issue similar to opencsv-not-reading-my-entire-file). I just changed the insert code to use BufferedReader to read the file and the delay disappeared!
