Hi All:
I hava a large Index repo, size is 47G, yes 47G , when I look up for something
in it , and then it is dead, I trace its execution as follows:
at
org.apache.lucene.search.TopFieldCollector.add(TopFieldCollector.java:1178)
at
org.apache.lucene.search.TopFieldCollector$OneComparatorNonScoringCollector.collect(TopFieldCollector.java:87)
at org.apache.lucene.search.Scorer.score(Scorer.java:62)
at
org.apache.lucene.search.ConstantScoreQuery$ConstantScorer.score(ConstantScoreQuery.java:238)
at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:588)
at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:555)
at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:507)
at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:484)
at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:309)
I think it is because my Index is too large , and all jvm heaps are used, and I
want to ask for some answers:
How I can reduce the memory which lucene used, Linux Top command result is as
follow:
top - 13:45:11 up 2:56, 3 users, load average: 0.59, 0.33, 0.51
Tasks: 193 total, 1 running, 192 sleeping, 0 stopped, 0 zombie
Cpu(s): 13.2%us, 0.2%sy, 0.0%ni, 86.5%id, 0.1%wa, 0.0%hi, 0.0%si, 0.0%st
Mem: 3933684k total, 3793900k used, 139784k free, 21704k buffers
Swap: 20482864k total, 490644k used, 19992220k free, 1408172k cached
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
5318 root 21 0 47.7g 1.6g 267m S 99.9 41.4 0:50.84 java
5536 root 15 0 596m 67m 5856 S 3.0 1.8 0:26.22 python
it is clearly Lucene load all index into memory, and I also know after this
query the memory is returned to OS, but just in this query, it is hung.
Could anyone give some suggestions about how to query large Index on a single
machine not distributed?
