मैं काफ्का 0.8.2 बीटा का उपयोग कर रहा है और 2 उबंटू 14 आभासी मशीनों:काफ्का Zookeeper कनेक्शन जारी करता
- 172.30.141.127 Zookeeper
- 172.30.141.184 चल रहा है एक काफ्का दलाल
मैं जुकीपर उदाहरण शुरू कर रहा हूं और सब ठीक है। फिर मैं ब्रोकर शुरू करने की कोशिश करता हूं और इसे 172.30.141.127 मार्च 181 से कनेक्ट करता हूं। ऐसा लगता है कि एक विशिष्ट बंदरगाह पर एक सत्र को जोड़ने और स्थापित करने में सक्षम है, लेकिन फिर यह कुछ अपवाद के कारण कनेक्शन को नुकसान पहुंचाता है जो लॉग प्रतीत नहीं होता है।

पिंग 2 मशीनों के बीच काम करता है। टेलनेट 2181 प्रकार के काम करता है, जिसमें यह कनेक्ट होता है, लेकिन समय-समय पर डिस्कनेक्ट हो जाता है। इससे मुझे लगता है कि समस्या जुकीपर उदाहरण के साथ है। दोनों प्रक्रियाओं को रूट के रूप में शुरू किया गया है।
कोई विचार यह क्यों हो रहा है? धन्यवाद
