Built Pinot locally and tested the patch by running the failing scenario as
follows:
1. Create `dataDir` and `segmentDir` directories with incorrect permissions
```
mkdir -p data
mkdir -p data/index
mkdir -p data/segmentTar
chmod 700 data
chmod 400 data/index
chmod 400 data/segmentTar
```
2. Start `server` with incorrect permission for `dataDir` and `segmentDir`
```
bin/pinot-admin.sh StartServer -dataDir data/index -segmentDir
data/segmentTar -zkAddress localhost:2191
```
3. We get error as expected now for `dataDir`:

4. Now fix `dataDir` permission and restart `server`
```
chmod 700 data/index
bin/pinot-admin.sh StartServer -dataDir data/index -segmentDir
data/segmentTar -zkAddress localhost:2191
```
5. We still get error for `segmentDir` as expected

```
6. Next, fix `segmentDir` permission and restart `server`
```
chmod 700 data/segmentTar
bin/pinot-admin.sh StartServer -dataDir data/index -segmentDir
data/segmentTar -zkAddress localhost:2191
```
7. `Server` starts smoothly!
