Subject Index partition corrupted during a regular flush due to FileNotFoundException on DEL file
Date Mon, 12 Sep 2016 10:31:57 GMT
Dear all,

 

Today we found one of our index partitions was corrupted during the regular
flush, due to the FileNotFoundException on a del file. The followings were
the call stacks from the corresponding exception:

 

[2016-09-12 16:40:01,801][ERROR][qtp2107666786-40854][indexEngine ] index

org.apache.lucene.index.IndexWriter.commit(IndexWriter.java:3451) 
org.apache.lucene.index.IndexEngine.flush(IndexEngine.java:409) 

 

My questions are:

l  Does anyone know the situation here? From the file system, I can’t find
the _oxep_7fa.del.

l  How about the life cycle of the del file?

 

Note: The Lucene Core is on 3.6.2.

 

Appreciated for your kindly advice.

Best Regards, Wenxing
