Subject FSImage from uncompress to compress change
Date Tue, 16 Jun 2015 08:28:55 GMT
Hi all!
My hadoop version is 2.0.0
In my hadoop configuration config the dfs.image.compress=false
Now the cluster has been running for a long time.
the fsimage size is growing. I want to compress the fsimage.
can I change the dfs.image.compress=true and 
dfs.image.compression.codec=xx.Codec and restart the namenode?
the no compress fsimage can be read? the data will lost or not ?

Thanks!
