Exception is thrown when using TimestampUpdateProcessorFactory

Hi All,

I am trying to get solr index time as solrtimestamp field.


<field name="solrtimestamp" type="tdate" indexed="true" stored="true"
omitNorms="true"/>

I am using solr 5.2.1 in solr cloud mode.


 <updateRequestProcessorChain name="script">
 <processor class="solr.TimestampUpdateProcessorFactory">
               <str name="fieldName">solrtimestamp</str>
  </processor>
      <processor class="solr.StatelessScriptUpdateProcessorFactory">
        <str name="script">update-script.js</str>
        <lst name="params">
          <str name="config_param">example config parameter</str>
        </lst>
 <str name="field">xnum,xnum2</str>
      </processor>
<processor class="solr.LogUpdateProcessorFactory" />
<processor class="solr.RunUpdateProcessorFactory" />
 </updateRequestProcessorChain>

But I am getting below exception when i run update or through DIH. Please
let me know how to fix this.

Hi Preeti,

Try adding a default attribute to the solrtimestamp field in schema and
check if this resolves the issue.
<field name="solrtimestamp" type="tdate" *default="<default_date>"* indexed=
"true" stored="true"/>
replace <default_date> with correct default date format

That's a really weird error.

I don't *think* Reth's suggestion will have any barring on the outcome, 
but i would love to hear if it changes anything.

the method name "getDefaultValue" in that stack trace is just 
because of how the class implements the general contract of a 
DefaultValueUpdateProcessor -- what that specific line is doing in 5.2.1 
is accessing the definition of "NOW" for the Solr Request -- metadata that 
is initialized when the request is first initiated (to ensure that a 
consistent value is used if, for example, multiple date based facets 
are computed i na single request, or multiple docs are added in a single 
request).

If you *only* got thsi error when using DIH, I would guess maybe DIH has a 
bug when it creates it's internal requests (because it's operating 
asynchronously) that prevents this value from getting initialized properly 
-- but you said "getting below exception when i run update or through DIH" 
... impliying that you get teh same exception when you do updates in other 
ways.

can you confirm/deny that you get a similar exception if/when you send 
updates *not* from DIH, and if so can you please show us the full stack 
trace of the error in that situation and provide some details regarding 
how you sent the update that caused that exception?
