NoNodeAvailableException and endless stacktrace in log4j when using TransportClient

Elastic Stack Elasticsearch
1

Hi all...

The following code, when I attempt to connect to a host that is down,
throws a NoNodeAvailableException.

No problem there - however, in getting to that point ElasticSearch
apparently recurses quite a lot, so that by the time it throws the
Exception, the stack is so deep that log4j complains about it being
too big, and I can't find the actual point of the problem...

try {
TransportClient client = new
TransportClient().addTransportAddress(new
InetSocketTransportAddress(myHost, myPort);

  SearchRequestBuilder builder = client.prepareSearch(index,

docType);
builder.setSearchType(SearchType.DFS_QUERY_THEN_FETCH);
builder.setQuery(new QueryStringQueryBuilder(queryString));
builder.setFrom(startIndex);
builder.setSize(maxResults);
builder.setExplain(true);
ListenableActionFuture future =
builder.execute();
} catch (Throwable t) {
// EXCEPTION HERE
}

If I just System.out.println() the caught exception, I see:
-- org.elasticsearch.client.transport.NoNodeAvailableException: No
node available

or if I call e.printStackTrace(), I see a reasonable-sized stacktrace.

However, if I try to print the stacktrace in log4j, I get:

java.lang.StackOverflowError
at java.lang.Throwable.getLocalizedMessage(Throwable.java:267)
at java.lang.Throwable.toString(Throwable.java:343)
at java.lang.String.valueOf(String.java:2826)
at
org.apache.log4j.spi.VectorWriter.println(ThrowableInformation.java:
181)
at java.lang.Throwable.printStackTrace(Throwable.java:509)

org.apache.log4j.spi.ThrowableInformation.extractStringRep(ThrowableInformation.java:
99)
at
org.apache.log4j.spi.ThrowableInformation.extractStringRep(ThrowableInformation.java:
99)

... ad infinitum.

I'm wondering what the stacktrace contains that might be causing
this... possibly many branching "caused-by" entries? Anyone else seen
this issue with log4j?

Do you have more stack trace when it happens in the log4j? See where the recursion happens?

Unfortunately not - if I do a printStackTrace(), I see a reasonable
stacktrace. But trying to print it with log4j gets the overflow
error.

I'll can post the stacktrace that printStackTrace() returns if that's
any help.

Got you, but, do you have more data printed as part of the stack overflow failure?
