> ShuffleHandler passes wrong {{base}} parameter to {{getMapOutputInfo}} if
> mapId is not in the cache.
> {{getMapOutputInfo}} expected the {{base}} parameter is
> {{getBaseLocation(jobId, user) + mapId}}
> When it is called inside populateHeaders, the {{base}} parameter is set
> correctly
> {code}
> String base = outputBaseStr + mapId;
> MapOutputInfo outputInfo = getMapOutputInfo(base, mapId, reduce,
> user);
> {code}
> When it is called outside populateHeaders, the {{base}} parameter is set
> wrongly to outputBasePathStr after number of mapId cached exceeds
> {{mapOutputMetaInfoCacheSize}}.
> {code}
> String outputBasePathStr = getBaseLocation(jobId, user);
> MapOutputInfo info = mapOutputInfoMap.get(mapId);
> if (info == null) {
> info = getMapOutputInfo(outputBasePathStr, mapId, reduceId, user);
> }
