Technical challenge posed.
One of researcher is faced with the following challenge. check if u
can help out
I m running the hadoop multi node cluster of 1,3,7 nodes. After
running 4 different MapReduce Jobs. the data blocks stored in one of
the datanodes have become more and its showing very less space,asking
to examine/delete the data contents. Hw to get rid of this problem? I
m running 3 nodes and 7 nodes , its showing filesystem corrupt by
missing blocks. Hw to increase the space in datanode?
can i delete the data in /tmp folder in datanodes(which shows less
space) ? or do i need to format the whole dfs? but all data contents
will be lost by this.
Plz do reply and suggest a solution for this.
