Hallo, I have a cluster of 6 nodes running hadoop0.19.3 and hbase 0.19.1. I have managed to write small programs to test the settings and everything seems to be fine.
I wrote a mapreduce program reading a small hbase table (100 rows, one familiy colum, 6 columns) and summing some values. In my opinion the job is slow, it is taking 19sec. I would like to look closer what is going, if the table is plit into tablets or not ...Therefore I appreciate if someone can answer my following questions: *Q1 -Does the value of "hbase.hregion.max.filesize" in the hbase-default.xml indicate the maximum size of a tablet in bytes? Q2- How can I know the size of the hbase table I have created? (I guess the "Describe" command from the shell does not provide it) Q3- Is there a way to know the real number of tablets constituting my table? Q4- Is there a way to get more information on the tablets handeled by each regionserver? (their number, the rows constituting each tablet) * Thank you for you help, CJ
