Hi Mark Miller Sorry to get you in these discussion . I notice that Mark Miller report this issure in https://issues.apache.org/jira/browse/SOLR-5734 according to https://issues.apache.org/jira/browse/SOLR-5721,but it just happened with the zookeeper. If I just do DIH with JDBCDataSource ,I do not think it will get the problem. Please give some hints
>> Bonus,just post the last mail I send about the problem: I have just compare the difference between the version 4.6.0 and 4.7.1. Notice that the time in the getConnection function is declared with the System.nanoTime in 4.7.1 ,while System.currentTimeMillis(). Curious about the resson for the change.the benefit of it .Is it neccessory? I have read the SOLR-5734 , https://issues.apache.org/jira/browse/SOLR-5734 Do some google about the difference of currentTimeMillis and nano,but still can not figure out it.
