Hi,
I am learning solr rencently, and I have some problems. Please help me and
I will thank you very much.
I stored indexes in HDFS directory, the update performance I got with
solrmeter showed that:
(1) the perfomance that storing index in local filesystem is about 7
timesbetter than the performance that storing index in HDFS (the block
replication of hdfs is 3 ).
(2) if I store index in hdfs, the preformance that setting the block
replication of hdfs to 1 is worse than the performance that setting the block
replication of hdfs to 3.
Could you help me to explain the performance difference? If the result I
got is wrong, How much the performance difference should be ?
Thank you very much.
Best regards.
