简而言之，当您使用的Java开发工具包（JDK）版本不支持线程分配内存时，会出现此错误。Elasticsearch使用此功能以获得更好的性能和内存管理。要解决此问题，您可以将JDK升级到支持线程分配内存的版本。或者，您可以在Elasticsearch中禁用线程分配内存的使用，但这可能会影响性能。最后，确保您的Elasticsearch和JDK版本兼容。
日志上下文 #
日志"thread allocated memory is not supported on this JDK"的类名是 HotThreads.java。我们从Elasticsearch源代码中提取了以下内容，供那些寻求深入上下文的人参考：
if (threadBean.isThreadCpuTimeSupported() == false) {
throw new ElasticsearchException("thread CPU time is not supported on this JDK");
} if (type == ReportType.MEM && sunThreadInfo.isThreadAllocatedMemorySupported() == false) {
throw new ElasticsearchException("thread allocated memory is not supported on this JDK");
} // Enabling thread contention monitoring is required for capturing JVM thread wait/blocked times. If we weren't
// able to enable this functionality during bootstrap; we should not produce HotThreads reports.
if (isThreadWaitBlockTimeMonitoringEnabled(threadBean) == false) {
