Fangyuan Deng updated KYLIN-3087:
---------------------------------
    Description: 
In GlobalDictionaryBuilder.init(),

this.builder = new AppendTrieDictionaryBuilder(baseDir, maxEntriesPerSlice, 
true);

if this line has exception, the DistributedLock will not release, and other 
jobs can not run.
so,I added a try catch.

        try {
            this.builder = new AppendTrieDictionaryBuilder(baseDir, 
maxEntriesPerSlice, true);
        } catch (Throwable e) {
            lock.unlock(getLockPath(sourceColumn));
            throw new RuntimeException(String.format("Failed to create global 
dictionary on %s ", sourceColumn), e);
        }


  was:
In GlobalDictionaryBuilder.init(),

this.builder = new AppendTrieDictionaryBuilder(baseDir, maxEntriesPerSlice, 
true);

if this line has exception,
