>
> When dfs.namenode.safemode.threshold-pct is configured to n
> Namenode will be in safemode until n percentage of blocks that should satisfy
> the minimal replication requirement defined by
> dfs.namenode.replication.min is reported to namenode
> But in UI it displays that n percentage of total blocks + 1 blocks are
> additionally needed
> to come out of the safemode
> Scenario 1:
> ============
> Configurations:
> dfs.namenode.safemode.threshold-pct = 2
> dfs.replication = 2
> dfs.namenode.replication.min =2
> Step 1: Start NN,DN1,DN2
> Step 2: Write a file "a.txt" which has got 167 blocks
> step 3: Stop NN,DN1,DN2
> Step 4: start NN
> In UI report the Number of blocks needed to come out of safemode and number
> of blocks actually present is different.
> {noformat}
> Cluster Summary
> Security is OFF
> Safe mode is ON. The reported blocks 0 needs additional 335 blocks to reach
> the threshold 2.0000 of total blocks 167. Safe mode will be turned off
> automatically.
> 2 files and directories, 167 blocks = 169 total.
> Heap Memory used 57.05 MB is 2% of Commited Heap Memory 2 GB. Max Heap Memory
> is 2 GB.
> Non Heap Memory used 23.37 MB is 17% of Commited Non Heap Memory 130.44 MB.
> Max Non Heap Memory is 176 MB.{noformat}
