Hi community, We have an issue with KafkaIO in the case of using a secure connection SASL SSL to the Confluent Kafka 5.5.1. When we trying to configure the Kafka consumer using consumerFactoryFn, we have an irregular issue related to certificate reads from the file system. Irregular means, that different Dataflow jobs with the same parameters and certs might be failed and succeeded. Store cert types for Keystore and Truststore are specified explicitly in consumer config. In our case, it's JKS for both certs.
Stacktrase: Caused by: org.apache.kafka.common.KafkaException: Failed to load SSL keystore /tmp/kafka.truststore.jks of type JKS at org.apache.kafka.common.security.ssl.SslEngineBuilder$SecurityStore.load(SslEngineBuilder.java:289) at org.apache.kafka.common.security.ssl.SslEngineBuilder.createSSLContext(SslEngineBuilder.java:153) ... 23 more Caused by: java.security.cert.CertificateException: Unable to initialize, java.io.IOException: DerInputStream.getLength(): lengthTag=65, too big. at sun.security.x509.X509CertImpl.<init>(X509CertImpl.java:198) at sun.security.provider.X509Factory.engineGenerateCertificate(X509Factory.java:102) at java.security.cert.CertificateFactory.generateCertificate(CertificateFactory.java:339) at sun.security.provider.JavaKeyStore.engineLoad(JavaKeyStore.java:755) at sun.security.provider.JavaKeyStore$JKS.engineLoad(JavaKeyStore.java:56) at sun.security.provider.KeyStoreDelegator.engineLoad(KeyStoreDelegator.java:224) at sun.security.provider.JavaKeyStore$DualFormatJKS.engineLoad(JavaKeyStore.java:70) at java.security.KeyStore.load(KeyStore.java:1445) at org.apache.kafka.common.security.ssl.SslEngineBuilder$SecurityStore.load(SslEngineBuilder.java:286) ... 24 more /tmp/kafka.truststore.jks is a path that’s used in consumerFactoryFn to load certs from GCP to the worker's local file system. Does anyone have any ideas on how to fix this issue? Thank you, Ilya
