Review Comment:
Its good to provide the exact rows as they exist in the metadata table, this
can not be done with String as it may mangle certain binary data. Could used
the TabletId type which already exist in the public api for this purpose.
```suggestion
public TabletId getTabletId(){
return new TabletIdImp(tabletMetadata.getExtent());
}
```

Review Comment:
I would move this to the shell code. Someone can call getNumEntries and
format it however they like when using the API, and there is good chance they
may not like the way this method formats the data.

Review Comment:
Since a tablet may not have a location, could have an optional return type
to make this clear.
```suggestion
public Optional<String> getLocation() {
```
Also as follow on issue, this could possible use the new type introduced in
#3626

Review Comment:
If the TabletInformation class took a tablet metadata in it constructor,
then this computation could be done in the constructor.

Review Comment:
If its workable it would be nice to make this object a wrapper around
TabletMetadata, then it does not need to duplicate alot of the fields.
```suggestion
private final TabletMetadata tabletMetadata;
public TabletInformation(TabletMetadata tabletMetadata) {
this.tabletMetadata = tabletMetadata;
}
```
