-----------------------------------------------------------------
Reopening since this is causing a test failure in the 2.x branch:
{code}
java.lang.NullPointerException
at
org.apache.nutch.parse.tika.TestImageMetadata.testIt(TestImageMetadata.java:73)
{code}
The relevant lines of the test are:
{code}
parse = new ParseUtil(conf).parse(urlString, page);
ByteBuffer bbufW = page.getMetadata().get(new Utf8("width"));
byte[] byteArrayW = new byte[bbufW.remaining()]; // <-- NPE
{code}
{{page.getMetadata().keySet()}} does not have "width" or "height." But, they
are extracted when running Tika directly (and on the 1.x branch).
I'm investigating why right now. But, seem to be going in circles.
Edit: Okay... So, for some reason, Tika's new GDAL Parser is being selected as
the Parser to use. That's why the metadata has keys like "Coordinate System."
We really want the ImageParser to be selected. I'm not sure why Tika selects a
different parser between the two Nutch branches. Nutch must call Tika slightly
differently between the two, leading to different (probably unintentional)
semantics from Tika.
Going to keep investigating. But, wanted to give an update.
