Data replication takes time due to large quantities of data. The Hadoop administrator should allow sufficient time for data replication depending on the data size. if data size is big enough it is not uncommon that replication will take from a few minutes to a few hours.
After increasing the replication level, I still see that data is under replicated. What could be wrong?
