> I've run into one problem while testing Tika 1.8-rc2 with Bixo
> It involves a dependency issue involving (of course) Guava, since that
> project loves to break their API :(
> The bixo-core jar has these transitive dependencies on various versions of
> Guava:
> Hadoop - 11.0.2
> Cascading - 14.0.1
> Tika-parsers - 10.0.1
> cdm - 17.0
> Everyone winds up using version 10.0.1 (note that Tika has a dependency on
> cdm, which wants to use 17.0)
> The problem is that Hadoop (for any recent version) uses an API from Guava's
> cache implementation that no longer exists:
> com.google.common.cache.CacheBuilder.build(Lcom/google/common/cache/CacheLoader;)Lcom/google/common/cache/LoadingCache;
> java.lang.NoSuchMethodError:
> com.google.common.cache.CacheBuilder.build(Lcom/google/common/cache/CacheLoader;)Lcom/google/common/cache/LoadingCache;
> at
> org.apache.hadoop.io.compress.CodecPool.createCache(CodecPool.java:62)
> at org.apache.hadoop.io.compress.CodecPool.<clinit>(CodecPool.java:74)
> at
> org.apache.hadoop.io.SequenceFile$Writer.close(SequenceFile.java:1272)
> at
> org.apache.hadoop.mapred.SequenceFileOutputFormat$1.close(SequenceFileOutputFormat.java:79)
> So what this means is that anyone trying to use Tika with Hadoop will need to
> play games with the class loader to get the older version of Guava - though
> that can cause other issues if Hadoop (or Cascading, etc) rely on anything
> that's only in the newer Guava API.
> Guava 10.0.1 was released about 3.5 years ago; 11.0.2 was from about 3 years
> ago. So it seems like we should upgrade to at least 11.0.2
