Description
i use solr with katta integration, pls see https://issues.apache.org/jira/browse/SOLR-1395
when i use:
ab -n 100 -c 10 http://localhost:8080/solr/select?q=solr&...
i found solr throws NPE, so, i added some code like below:
ipc.Client.Connection
public void receiveResponse() { ... try { ... ... } catch (IOException e) { markClosed(e); } catch (RunTimeException t) { LOG.error("Unexpected error reading responses on connection ", t); throw t; } }
then, i catch the ClassNotFoundException:
java.lang.RuntimeException: readObject can't find class om-SL510?(responseê`?$name... at org.apache.hadoop.io.ObjectWritable.readObject(ObjectWritable.java:185) at org.apache.hadoop.io.ObjectWritable.readFields(ObjectWritable.java:66) at org.apache.hadoop.ipc.Client$Connection.receiveResponse(Client.java:511) Caused by: java.lang.ClassNotFoundException: om-SL510?(responseê`?$name... at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:247) at org.apache.hadoop.conf.Configuration.getClassByName(Configuration.java:762) at org.apache.hadoop.io.ObjectWritable.readObject(ObjectWritable.java:183)
