> In doing read operations with ACL we were checking there is read permission granted on the table
> {code}
> AuthResult authResult = permissionGranted(opType, user, env, families, Action.READ);
>     HRegion region = getRegion(env);
>     TableName table = getTableName(region);
>     Map<ByteRange, Integer> cfVsMaxVersions = Maps.newHashMap();
>     for (HColumnDescriptor hcd : region.getTableDesc().getFamilies()) {
>       cfVsMaxVersions.put(new SimpleByteRange(hcd.getName()), hcd.getMaxVersions());
>     }
> {code}
> If there is no permission then we were checking for the type of cell level permission 
> {code}
> case CHECK_CELL_DEFAULT: {
>         if (authManager.authorize(user, table, family, qualifier, Permission.Action.READ) ||
>             authManager.authorize(user, table, cell, Permission.Action.READ)) {
>           return ReturnCode.INCLUDE;
>         }
>       }
>       break;
>       // Cell permissions must authorize
>       case CHECK_CELL_FIRST: {
>         if (authManager.authorize(user, table, cell, Permission.Action.READ) &&
>             authManager.authorize(user, table, family, qualifier, Permission.Action.READ)) {
>           return ReturnCode.INCLUDE;
>         }
> {code}
> For CELL_FIRST_STRATEGY 
> -> if the user had granted READ permission on the table itself then even if cell level was not granting access we were able to read the cell.
> ->If table level READ permission was not there then the && condition was failing from reading any cell even with READ permission. 
> The 2nd one was an intended behaviour but for the first one I think we should see if really the cell was readable too.
