Hi All,
I have a doubt in hadoop secondary namenode concept . Please
correct if the following statements are wrong .
The namenode hosts the fsimage and edit log files. The secondary namenode hosts
the fsimage file only. At the time of checkpoint the edit log file is
transferred to the secondary namenode and the both files are merged, Then the
updated fsimage file is transferred to the namenode . Is it correct?
If we run the secondary namenode in separate machine , then both machines
contain the fsimage file . Namenode only contains the editlog file. Is it true?
Thanks R.Shanmuganathan
